A Year’s Labour

Naturally dyed wool

This week there’s been a hint of spring in the air and we haven’t even had a storm for a whole week, which makes a nice change. In the garden it is starting to feel like the beginning of a new season. But before I get too enthusiastic about making plans for a new dyeing season, I want to take a moment to show you what I achieved last year.

I had many ambitious dyeing plans for 2013. I wanted to try some plant-based mordants like rhubarb leaves and willow, I wanted to try dyeing new fibres like silk and cotton. And there was a very long list of dye plants that I was going to grow and dye with. Well, as so often happens in life, it didn’t quite work that way. After a serious relapse with my ME/CFS in the spring, for a while it looked like I might not be well enough to do any dyeing at all.

But by July, I had picked up sufficiently to make my way back to the dyeing shed again. Even so, doing the dyeing process the usual way over a day or two was still too strenuous for me to manage, so instead, I broke it down into lots of smaller steps, and did each step on a different day. For example, normally you would pick your plant material, chop it and then proceed to simmer it straight away, but I wouldn’t have the stamina to do both of them on the same day. Instead, I would pick and chop the plan stuff, put it in a pot and cover it with water, then wait for few days before continuing. This way the process might have been frustratingly slow, but with this illness you just need to learn to be patient. It’s either that or not do anything at all…

So with some very careful planning and lots of self-discipline (to stop myself  over-enthusiastically overdoing things and flattening myself as a result) I managed to have a couple of reasonably good months of dyeing before the autumn arrived and my energy levels collapsed again.  In the end I did not get to try rhubarb or willow mordants, or cotton dyeing for that matter, but I did get to try silk and several different dye plants that I hadn’t worked with before: purple basil, cutch, annatto, Lady’s Mantle (Alchemilla mollis), dahlia, tagetes, black hollyhock, Japanese indigo as well as my first mushroom dyeing experiments with Cortinarious semisanguineus. Some of these I have already written about, the others are still on the To-Do List waiting for a spare moment.

Naturally dyed Finnsheep top

A year’s worth of dyeing experiments. Finnsheep top, all in naturally dyed colours.

My plan was to focus was on experimenting with as many different dye plants as I possibly could, and try to see how many colours I could get from each one of them. I would vary the colours by trying different mordants (alum and copper) and different modifiers (iron, acid and alkaline baths). I was very much in a sampling mode, and to keep the costs (as well as my stash) under control, I didn’t dye anything in large quantities. For sampling I used small pre-felt squares as they are quick and economical to prepare.

As I was focusing on small quantities, I also thought it would be an ideal year to dye some embroidery threads. So I spent the spring when I was too unwell to do anything that requires lots of brain power making lots and lots of mini skeins in both silk and wool that during the summer got thrown into the dye pot along with my usual Finnsheep top. The woollen yarn was intended as a Christmas present for my dad, who likes using wool in his needlework projects.

Given that I was trying to produce lots of different colour variations on several different types of materials, I had to devise a good system for keeping track of what exactly I was doing (especially since my memory is like a sieve, and I easily lose my concentration if I get overtired). But after a few weeks of dyeing I had established a method that worked for me. After a dye bath had been prepared, I would divide it into two lots: one for alum mordanted materials and another for copper mordanted ones. Into each alum pot I would throw in 5 pre-felt squares, 5 skeins of silk in two different weights, two skeins of wool and some Finnsheep top. The copper pot would get the same except the top (I chose not to mordant my top with copper, as I wanted to keep the copper mordanting quantities as small as possible, as it is more toxic than alum).

Then, after dyeing, I would set aside one alum mordanted piece of each type of material, and then modify the rest using acid, alkaline, iron and copper. The copper samples would get the same treatment (except the copper modification which would obviously be pointless). As a result, for each dye, I would get 5 different shades from alum and 4 from copper, both in silk and wool. And obviously the dye bath could be re-used a few times, which would get you another lot of colours but in a lighter value. To keep track of all these different versions I use numbered and coloured pegs (having said that, I did lose track quite a few times and ended up with random colours that I had no idea of how they had been produced).

I decided against modifying my spinning wool in any way. This is because colours modified with acid and alkali are not always stable and they easily change in the wash. I know it is recommended that you use a pH neutral detergent, but I’ve never found a detergent so neutral it doesn’t affect the colours, especially the ones that have been modified with acid. To keep the acid-modified colours, you would need to rinse them with vinegar after every wash. But if you combine acid and alkaline colours in the same project, this obviously isn’t possible. When I spin wool,  I like blending different colours on my carder, so it would be waste of effort to create lots of tonal variation that you are just going to lose afterwards in a wash. Colours modified with iron are more stable, but I am slightly worried that if I combine iron-modified colours with plain alum ones, the residual iron might contaminate and sadden the alum colours (although I must say I have never tested if this really happens). But for all these reasons, I stuck to alum colours only with my spinning wool. It is always possible to use iron afterwards for specific projects if necessary.

Naturally Dyed Fibres

Another lot of dyeing results waiting to be photographed

After about two months of these experiments, I started getting a bit impatient and even bored of my method of trying one new dye plant after another. I seemed to be getting an endless amount of mustard yellows and golden browns – nothing wrong with these colours at all, but lets face it, there’s only so much you really need. And so I noticed my thinking was beginning to shift: I no longer wanted to tick off as many plants from my list as I possibly could, I felt that I had done enough of that. Rather than structure the process around plants, I realised it would be far more useful start focusing on colour families and the colour circle – blues, reds, yellows as well as all those colours that require over-dying like grassy greens and purples.

But by the time my thinking had evolved to this point, it was late autumn, the weather was getting colder and wetter and it was not quite as much fun to hang around in the dyeing shed anymore. And my strength was beginning to diminish again, each dyeing session (especially the indigo ones) would leave flattened for days and I realised that it was probably best to stop for now and  wait for times when I have more stamina again.

So all in all, it was a good year of dyeing and I learned lots. If and when I am well enough to start the process again, I will definitely be focusing on a smaller set of dye plants (perhaps those classic ones that are known to be colour-fast) and experimenting with producing more complex colours by over-dyeing. I already made a good start with over-dyeing yellows with indigo to produce bright greens, but learning to create purples with conchineal and indigo will be on my list too. And maybe I will get round to trying cotton dyeing too…

More Purple Basil Surprises

Some time ago I showed you the results of my purple basil experiments this summer. Well, that dye bath went quite a bit further and I was able to have several other experiments with it, all of which threw quite a few surprises into the process.

Given that purple basil seems to be better suited to dyeing silk than wool (wool just doesn’t seem to absorb much colour) I decided I won’t waste the dye on wool but try more experiments with silk instead. I had a dig around in my cupboards and found a cream coloured Thai silk scarf, a souvenir from a lovely holiday a long time ago. So in it went (after scouring and mordanting with alum), and after an hour of simmering, out it came very dark, almost black. As my hope had been a nice slate grey, a medium tone rather than a very dark shade, at first I kicked myself for not paying attention to dye rations and therefore for using way too much dye. Considering the scarf weighs only 45g one could have anticipated that not much dye is needed. A good lesson to learn, especially when dyeing finished items, rather than random amounts of economy wool…

But as I removed the scarf from the pot and the excess dye drained away, I realised the colour I had accidentally achieved was in fact truly beautiful, a sort of raven black: a very dark grey with a strong blue sheen or undercurrent to it.

And there were more surprises in store: as I washed the scarf, the alkalinity of the wash turned the colour into something else entirely: it was now a very dark jewel-like green, a regal green as my husband observed. It was a fantastic colour, but I wanted that raven blackish blue back so I soaked the scarf a vinegary water for a few hours.  I played around with different levels of acidity just to see how it affected the colour, and eventually, settled with a medium grey tone.

And once it dried, the grey in fact had a beautiful midnight-blue undertone and  a wonderful depth to it. The colour seems to change depending on the light, and it was very hard to capture the colour correctly on my camera, in the picture below it looks perhaps a bit lighter and bluer than it is in real life.

Next I wanted to find out what would happen if I used the exhaust bath to dye some wool-silk blend yarn. After all, if wool gives you pale greyish green, and you get darker greys with silk, surely the result would be a nice heathery mixture of darker and lighter shades? Well, it didn’t quite work that way.

The skein I used was a mixture of 55% Blue Faced Leicester wool and 45% silk (undyed Decadence Heavy Lace yarn from the Stash Fine yarns). Unfortunately, the bit I didn’t really think through properly in advance was that the BFL wool was superwash, which absorbs colour differently compared to non-treated wool. So in the end both types of fibres absorbed the colour very strongly and I ended up with quite a darkish shade of medium grey.

As I thought this colour was a bit dull, I washed the skein and hoped it would turn a nice dark greeny grey, but no, it was still just a dull grey colour, just a little undercurrent of greenness in it. Then I tried a soak in vinegary water to try to turn it purple, but again, it wasn’t really co-operating, there was a slight change, but when dried, the colour had reverted to medium grey. And when, some time later, I photographed the skein, I noticed that in the outdoor light there was a distinct green tinge to it again, so I am now wondering if the colour shifts slightly even when dry. Obviously this is the colour it wants to be, so I left it for a moment (although I am still not too keen on it – it looks better on the picture than in real life – so I may give the skein a dip in an indigo vat next).

Even after all these experiments there was still quite a bit of dye in the bath left, so I decided to throw a bit more wool into the pot, but again there was a surprise in store. Rather than getting greenish grey, I just got plain straight-forward fawn, never the most exciting colour to get, but at least in this case there was the surprise factor, as I really don’t know why I suddenly started getting an entirely different colour compared to what had happened before. I even threw a few bits of silk fabric into the bath and they too came out more fawn than before, although it was more like a greyish fawn mixture, a bit like the colour of wood smoke. I’d love to know why this happened: was it that a particular pigment was now used up, or was it just the age of the dye bath, after all it had been stored, and occasionally simmered, for several weeks now?  I don’t know the answer to that, but I suppose it is just another reason why natural dyeing is such an endlessly fascinating subject.

I certainly wasn’t expecting fawn…


Dyeing with Alchemilla Mollis

Alchemilla mollis

Alchemilla mollis is one of the star plants in my garden. Not because it is a prima donna-showstopper, but because it is such a good doer, an easy-going plant that seems to be happy anywhere. It may not be a attention-grabber like a more showy plant like a rose would be, but it is a trustworthy filler plant with its lime green frothy flowers that look great with anything.

In our heavy clay soil that is frequently either water-logged or dry as concrete it is the most reliable plant that I have, surviving in conditions (like dry shade) where other plants just give up. And as it self-seeds quite readily, I have little Alchemilla plants popping up everywhere, which I am more than happy about because I just move them wherever I happen to have a gap in my flower beds. And I love the way it looks like in a vase, so natural and pretty, and it lasts easily for two weeks. A most useful garden plant, in other words.

Given that I have Alchemilla everywhere in my garden, I was delighted to learn from Colour Cottage that you can also dye with it (thank you Pia for the tip!). So when the time came to cut it back after flowering, I had lots of material to use in my dyeing experiments.

I simmered a pot full of Achemilla leaves and flowers for about an hour. Once the dye liquid had cooled, I added some wool and silk into the pot. I didn’t have the time to simmer them at this point, so I just left the pot for a week (well, actually it could have been more like two before I got round to dealing with it, it was beginning to have some mould on top if I am completely honest with you…).

dye samples - Alchemilla mollis

Alchemilla mollis gives you soft mustardy yellows with alum and not very exciting browns when you mordant with copper. It doesn’t respond much to pH, acid makes it slightly paler and alkali slightly more intense, but the difference is not so great I’d bother using these modifications in the future. My alum+iron+alkali sample mysteriously got lost in the process.

This year, to control the costs (as well as the size of my yarn stash) I decided to try all the different colour modifications (ie. after-baths with acid, alkaline or iron) on little pieces of felt rather than yarn. Given that not all dyes respond to pH for example, you can end up with lots of wool of very similar colour and I felt using large quantities of yarn for these experiments was a bit too yarn- and money-consuming. And I got fed up with making lots of little sample skeins, as I would need so many of them (8-12 for each plant) and it’s tedious and time consuming process to be make. Felt samples are quick to prepare, and if the experiment results in dull colours it doesn’t really matter too much.

For similarly frugal reasons, my main dyeing material at the moment is Finnsheep top, using unspun wool is more versatile than yarn as I can either spin it into yarn of any thickness I like or I can felt it. I do dye some yarn too, but only small quantities for specific purposes.

Despite all that I still couldn’t avoid having to make some little sample skeins though, as this year I wanted to try dyeing some silk and I though building a naturally dyed embroidery silk collection would be a great way of experimenting with silk dyeing. Not that I am a big embroiderer at the moment, but it is something I’d like to do more of (one of these days when I have the time and energy) and obviously this gives me an excuse to build (yet) another stash.

I haven’t dyed silk before, so I was delighted to discover how it just soaks up colour, the colours somehow look more intense compared to wool (and it’s interesting to note they are not always the same as with wool). And the complex colours of natural dyes go beautifully with the luxurious lustre of silk, I just love the results. To mordant silk I use exactly the same method I use with wool. I cold mordant it with alum formate or simmer it with copper and citric acid.

The colours you get with Alchemilla mollis are not necessarily that remarkable – after all you get yellows from so many plants. And the copper mordant gives you slightly uninteresting browns. But I particularly like the softness of the yellow you get with alum, it is not bright and brash at all, slightly mustardy just to make it look a bit more interesting than a standard bright yellow. A wonderfully complex colour so typical of natural dyes. And if you go easy on the iron (not like in my felt samples that went nearly black), alum mordanted wool becomes a nice soft olive green. I am thinking one day I’d quite fancy a jumper or a cardi in one of these colours, which is quite doable as I have so much of this plant around.


Harvest Time

dahlias and chamomile pickedAh, harvest – that time of the year when the hard work earlier on is finally beginning to pay off. That time of the year when the greenhouse is full of cucumbers and tomatoes, and after a month of eating courgette with every meal you frantically search around the internet for any new exciting courgette recipes that you haven’t already tried (note to self: five courgette plants in a household of only two people is definitely way too many!). That time of the year, when you are just about ready to start picking all those gooseberries that you have so anticipated being able to eat, just to notice that they have suddenly been eaten by some mysterious nocturnal beastie – just like that – over night – with not a single one left.

drying flowers for dyeing

I dry many of my dye plants for later use. My netting tower is completely stuffed at the moment.

Despite some of the challenges in my dye garden that I wrote about in my last post, there is plenty of material there to be getting on with. If I am planning on using flowers for dyeing, I rarely use them fresh as I don’t often have enough at any given point for a decent batch, so I dry them and use them once I have accumulated enough. So flower harvesting has been the number one hobby this month.

After a cold first half of the year, the weather has finally realised it has some catching up to do so we have been having an unusually long heatwave here in the UK. As lovely as it would be to spend the warm evenings lounging around in a deck chair, enjoying a glass of wine, the reality hasn’t been quite like that (I suppose it never is).

The hotter it has been the more work there has been in the evenings, trying keep all my new plants watered and alive. So I have been spending my summer evenings rushing around with a garden hose, then with legs already seriously wobbly, picking up all the flowers that are past their best and trying to find a flat surface for them in the outbuilding that is not already covered with flowers.

Actually, despite the element of franticness in trying to get everything done before collapsing completely, I really do like that bit. On a sunny evening there is definitely a moment of serenity there, with the sun going down, the air cooling and my plastic crate being filled up with wonderful colours. That’s my favourite part of it all.

A month or two ago I was slightly worried that I might not have the stamina to do any dyeing this summer at all, but luckily my energy levels have picked up a little bit (perhaps it is all that sun and vitamin D) and now, after all the essential house and garden jobs (and all that plant watering) are done, there is just enough energy left over to do a bit of dyeing.

I love solar dyeing, just chuck stuff into a jar and leave them until you are ready to continue with the process. In this case I have pre-boiled the plant material though, as I find that decomposing plant bits can stick to unspun wool easily if you leave it for too long (as I often do).

In this case I have pre-boiled the plant material and discarded the plant bits before placing the dye liquid in the jar, as I find that decomposing plant bits can stick to unspun wool easily if you leave it for too long (as I often do).

It is going slowly, and it feels quite strenuous at the moment, so the materials are often left in dye pots for days before I have the energy for the next stage, but that doesn’t matter. That’s the thing I like about natural dyeing, it’s pretty flexible in that you can stop the process in many places and wait for a few days (or even weeks as the case may be) before you continue.

Given that it is going so slowly, I haven’t quite got to the stage where I am ready to show any actual results, but meanwhile I thought I’d give you another quick tour of the harvesting activities that have been going on.

It’s an Addiction

And this dyeing season, I'm going to need approximately 10 000 sample-size skeins

And this dyeing season, I’m going to need approximately 10 000 sample-sized skeins

Given that this spring has been the second coldest on record, and so far there’s no sign of the weather getting any warmer or sunnier (it’s snowing here even today), my dyeing season hasn’t really got started yet. I dye in an unheated outbuilding which has no window, so it’s not really a place where I fancy hanging around in cold and damp weather. But my dyeing fingers are definitely getting very itchy by now, so I have been using this seasonal delay in getting super organised and prepared.

Last year was my first dyeing year, and I started like every does, full of enthusiasm and no idea what I was doing, and improvising as I went along. But towards the end of the season, I had established a way of working that suits me and was naturally getting more organised about it. I also learned that natural dyeing definitely brings out the inner scientist in me, I like trying to get as many colours from a particular plant as I can, and enjoy experimenting with different mordants and modifiers. And as I am still very much a beginner, there are so many dye plants that I haven’t tried yet, so this year I am trying to grow an even longer list of plants to try, as I wrote here (well as long as my seeds just agree to co-operate and germinate in this cold weather).

This year, having learned the basics, I also want to take my dyeing experiments even further. I want to try new types of materials,  such as silk and cotton, and cotton being a plant fibre of course requires learning about how to mordant it. I also want to try making my own mordants from plants such as willow and rhubarb leaves. So this season, if all goes to plan, in any given dyeing session there will be a lot of more fibre types and several different mordants to take into account.

Although systematic experimentation is a great method for learning about natural dyes, it also does require quite a bit of organisation, not least because you need to have lots of skeins  and those skeins need to be labelled carefully, otherwise you lose track of them very fast.  With wool, if I am trying a new dye plant I normally try to get at least 6 colours per dye and mordant combination: for example when using alum, I’d need skeins for the following combinations

  • plain dye colour just using alum
  • alum with iron modifier
  • alum with acid modifier
  • alum with alkaline modifier
  • alum, acid and iron
  • alum, alkaline and iron

So that’s 6 skeins per mordant, and if I want to try willow and rhubarb mordants, as well as the usual alum and copper, then for any given dye, I’d need at least 24 different skeins. As you can see the amount of skeins you need for this approach can get out of hand very quickly. The only way to make it manageable from a cost point of view would be to use either very small skeins (which take a lot of time to make), or perhaps use small squares of fabric just for sampling purposes. I may well end up using fabric rather than yarn samples as they take less time to prepare, but since I promised my dad I’d dye a nice range of colours for his needlework this year and I also would like some naturally dyed embroidery silks for myself, then I won’t be able to avoid having to make lots and lots of mini skeins.

Last year I remember reading about a dyer who would get all her mordanting done in the early summer while waiting for her dye garden to start producing materials to dye with. I remember thinking, wow, that’s so organised, but I would never be able to manage that, I’d never think of it on time. But obviously this idea has been percolating in my head as recently I have started thinking it might actually be a good idea, especially as some people believe that doing mordanting several weeks if not months ahead of the actual dyeing will improve the results.

So this year I am going to have a go at separating the mordanting process from the dyeing process, which makes sense if I will be working with at least 4 types of mordant for wool and perhaps a few more for the cotton fabrics. And since I am mainly growing my own dyes, then mordanting early in the season definitely fits well into the natural seasonal rhythm of things. It may be a bit dull first, but by the time your garden is bursting with plants, you can just concentrate on dyeing.

And being well prepared may well be the only way I can manage carrying out these grand experimental plans, especially since the dyeing process is physically quite strenuous for me (because of my ME/CFS) even if I keep it simple with using just one mordant and one type of fibre . A long day at the dying workshop just isn’t an option for me, so I need to break down the process into smaller steps and being organised is the only way I can reconcile such grand plans with a limited amount of energy.

But I’m not entirely convinced that I’ll be able to pull it off being so organised and systematic all summer, I wouldn’t be surprised at all if in the end I just ended up chucking random materials into my dye pots, not bother with labelling anything and instantly forgetting what exactly I had been doing.

It’s a bit like gardening. Early in the season you have great plans, and as the season progresses you get more and more overwhelmed with all the seedlings and plants and the amount of work and watering they need. By July, each year I make a solemn vow not to make such big plans ever again. And all winter, I keep thinking “I will resist making big plans, I will resist making big plans, I will resist… “.

Yet, by the time spring comes,  first I get the grand new ideas, then the delusion that this year it will be different, of course I will be able to do all those wonderful things,  because this year I am going to be so much more organised than I have ever managed before. There will be no problems whatsoever…

And so, every single year I end up with plans even grander than the year before. I don’t what it is about me and making over-ambitious plans, I just feel compelled to make them even if I know I already try to do much more than I can possibly manage. Focus and prioritisation just seem way beyond me. And this year, I’ve been going through a bit of a rough patch with my ME, and yet, here I am, completely unable to resist planning for some great new achievements.

And who knows, perhaps this year I will actually succeed.


New Plans for My Dye Garden

Planning the new season in my dye garden

With my trusted dyeing books and a few packets of seeds, I’m ready for the new season in the garden!

It has been a cold and grey spring here so far. We had two wonderfully sunny days last week, the crocuses and bees were out at last, but unfortunately it didn’t last.  This week the winter is back we had 10cm of snow on the ground this morning. But it’s prime seed sowing season nevertheless, and it has been keeping me busy in the last few weeks.

To avoid the inevitable spring rush, I was super-organised in the autumn and ordered my seeds already then. And yet, as I have been going through those seeds now, I realised that some of my seeds should have been sown already in the autumn, and quite a few need a period of cold before they germinate. I can’t believe it – I’m behind already and I have only just started!!

Last year was my first year of growing dye plants, and this year I have an even bigger list of plants I want to try to grow. I have a new border dedicated to dye plants, which is pretty exciting. As well as useful, I want this border to be ornamental too so I have chosen plants that look pretty as well as are suitable for dyeing. I am also going to scatter a few of these multi-functional plants  in my existing ornamental flower borders (just to have even more room for them!).

So here is the plan for dye plants that I am going to grow this year. Just for my own benefit so that I remember what I should be doing, I’ve grouped the plants according to sowing time and method.

Seeds that need an early sowing:

  • Japanese Indigo (Polygonum tinctorium). After my success with woad last year, I’m very excited to try the Japanese indigo this year.This needs a long season especially if you want the plants to set seed. It is not hardy so I have started these in-house, soon I will move them to heated propagators in my unheated greenhouse and hope to keep them going that way until late May when I will plant them out.
  • Dyer’s Broom (Genista tinctoria), this will need an exposure to cold before germinating. After sowing, I kept the seeds in the house for 2 weeks, then put them outside for the chill treatment. And I already have a few plants in pots that I managed to grow last year, but never had the time to plant somewhere permanent.
  • Purple loosestrife (Lythrum Salicaria). This is a pretty native plant with purple flowers that is ornamental as well as suitable for dyeing. It needs damp soil, which luckily we have. We have a pond in the garden as well as very sticky clay, so by the pond it is often completely soggy. Seeds should be sown in winter in a coldframe.
  • Goldenrod (I’m trying Solidago canadensis ‘Golden Baby’). Seeds should be sown in late winter/early spring.
  • Black-eye Susan (Rudbeckia fuldiga ‘Goldsturm‘). Sowing in early spring in a cold frame.

Spring sowing (seeds to be sown in spring in a coldframe or in an unheated greenhouse):

  • Hemp Agrimony (Eupatorium cannabinum). This is a very tall perennial that butterflies adore. It can also be used for dyeing. Seeds can be sown in a cold frame or unheated greenhouse in the spring.
  • Medowsweet (Filipendula Ulmaria). Another multifuctional plant that needs damp conditions ideally by a pond.
  • Tickseed (Coreopsis tinctoria). A perfect multi-functional plant that I grew last year. It looks pretty and gives a nice range of yellow, oranges and brick red as I wrote here.
  • Purple basil (I am trying variety ‘Purple Ruffles’). Not a hardy plant so needs to started indoors. My soil is not ideal for basil, but I am going to try it anyway, and perhaps keep some in pots.
  • Red Perilla. This is an oriental cooking vegetable that is decorative too. The seeds only germinate after their dormancy is broken. Apparently keeping the seeds in a fridge for 1-3 months before sowing might do the trick. So I am putting them into the fridge now and sow a bit later on in the spring.

Direct Sowing (March to May):

  • Bronze fennel. A truly multi-functional plant, very ornamental, used in cooking and also dyeing. The seedling of fennel do not transplant well so it’s best sown directly in late spring.
  • Woad (Isatis tinctoria). Last year I was more successful with my woad when sown directly (the seeds I tried to propagate in the greenhouse just didn’t germinate). It’s a hungry plant so needs extra fertiliser once it gets going.
  • Weld (Reseda luteola). Another one that I just could not get to germinate in the greenhouse last year, so this year I am going to try sowing it directly in a dry gravelly ground next to the south facing wall of our garage – lets see if I am more successful this way.

Plants that I already started last year:

  • Dyer’s Chamomile (Anthemis tinctoria). This is a perennial plant so it should flower again this year.
  • Black Hollyhock (Althaea rosea var. Nigra). As I have been reading about the dyeing experiments by Pia from Colour Cottage with this plant, I am so happy I already started some plants last year. It’s a biennial so mine should flower this year.
  • Rhubarb. I planted quite a few rhubarb plants in my kitchen garden last year. As well as the stems that provide nice puddings, the leaves (which are poisonous) can be used as a mordant. The roots you can use as dye. But you are supposed to let them grow 2-3 years before starting to harvest them so I may need leave mine alone this year.
  • Buckthorn (Rhamnus species). This is a hedging plant, and I am going to fill some gaps in our hedge with some plants that I bought last year and have been growing on in pots.


  • Elder (Sambucus nigra). I’m going to plant both the green and black varieties in my garden this year. The flowers and berries can be used in cooking and the leaves and the flowers can be used in dyeing.
  • Blackthorn, “Sloe” (Prunus spinosa). There’s a wild sloe bush in the forest near our house the berries of which we’ve used to make wonderful sloe gin but I’d like a sloe bush in my own garden too.

And in case I won’t have enough on the list already, I really would like to try these too:

  • Dahlia
  • Staghorn sumac (useful as a mordant too)
  • and some hardy variety of eucalyptus

Now that I am looking at this, I’m realising it’s quite a list. I am always way too over-enthusiastic and ambitious with my garden plans and by April I know I am in trouble. Despite good intentions this happens every year, so I’m sure this year won’t be an exception. But being sensible  is not fun, is it?


Green (or not)

A few weeks ago when we were taking down the decorations from the Christmas tree, I had a brilliant idea: I’m going to use the remains of the tree to dye some wool. After all, I had dyed with fir in Finland over twenty years ago when I first experimented with natural dyes. I can’t remember any more what the basic colour was (possibly olive green?), but I seem to remember that with iron you get a nice dark grey.

Because of the different climate, conifers are not nearly as common here in the UK as they are in Finland. Here in Kent you only really see them if someone has planted one in their garden, so getting hold of fir for dyeing is not that easy.  Now I realise the species of fir they sell as a Christmas tree here (typically Nordman fir) is not the same as the common fir tree in Finland (which is Picea abies), but I though it’s nevertheless worth having a go.

So I chopped up some branches and soaked them for a few days, then boiled them for about an hour. And this is the colour of the water I got:

well it was worth a try…

Not very hopeful, is it? Given that there’s hardly any colour there, I think I will abandon this experiment and not even try to dye with it.


So instead of showing you some beautifully dyed yarn, I’m going to have to find something else to show you today. And this one sort of fits with the green theme. It’s a table runner that I sewed for my sister-in-law for her Christmas present. I made two of them so that you can use them instead of table mats.

The inspiration for these table  cloths came from my sister-in-law herself as she had sewn a similar set for me a few years ago. The material she chose was a great Marimekko classic, Tantsu (a similar fabric also goes by the name of Satula). I just love its strong and vibrant colours.

Tantsu comes in several beautiful colourways, but this one is a vibrant mix of magenta and bright red
