Green Variations

One of the great things about natural dyeing is that you can keep overdyeing until you get the color you want.

~

I recently dug out some green skeins of Norne that were not exactly what I had imagined, and had been sitting in the storage basket for a while. I decided to overdye them to get as many greens as possible. So I wound skeins for dyeing and kept the last part of the skein the way it was.

One skein (skein 1 in photo below) was a medium blue from indigo overdyed with a couple of afterbaths from pomegranate and weld. They gave a rather weak yellow, too weak to match the blue tone, resulting in a quite anemic green.

Another skein (skein 12) had the same problem. Again, a medium indigo blue, this time over dried mugwort dye. I didn’t know at the time I dyed this (as I do now) that dried mugwort only gives a rater weak beige.

Then there was a skein with the opposite problem (skein 5). It’s dyed with a strong (1:1) weld and overdyed with weak indigo, giving a green/Chartreuse that’s just too intense.

Finally, there’s a skein that was actually a good color (skein 9) but I just didn’t have any plans for it. I dyed it long ago with tansy and a madder afterbath to achieve a warm yellow. I wound all the skeins into smaller ones and overdyed them with indigo, weld, and walnut hulls.

Overdyeing and then some more overdyeing, to get as many greens as possible.

Skeins 6, 7, and 8 come from skein 5 and are just overdyed with stronger and stronger indigo, and there’s no surprises there. The strong yellow base ends up as a clear forest green when the indigo component becomes large enough.

Skeins 10 and 11 are yarn from skein 9 overdyed with a bit of indigo and a bit more. Here, skein 10 was a nice surprise, a wilted green, one of my favorite shades of green. I suppose I am really revealing myself as totally ignorant of color theory, but I did not know that this type of green contains such a large proportion of red.

I made a dye bath with 12 g of weld and dyed 25 g of yarn from skein 1 in it. That turned into skein 2 – not a surprise that the forest green emerges when you lift the level of yellow to match the blue in intensity.

Then I made a dye bath with 25 g of walnut hulls. 25 g of yarn from skein 12 turned into skein 13. Again, the ignorant dyer was surprised – turns out army green is based on brown. The afterbath turned yarn from skein 1 into skein 3, another army green.

Skein 4 is yarn from skein 1, overdyed with a rather intense indigo. Here, the weak yellow base gives a really nice teal. Skein 14 is yarn from skein 12 just overdyed with a bit more indigo than it already was.

Finally, there’s skein 15. The yarn comes from skein 12, and was first dyed in the weld afterbath. It didn’t change much, so I dyed it in the walnut hull bath, which had already been used twice. Again, not much change, so I dipped it in indigo. That still didn’t change much so I left it because I ran out of ideas.

Skein 16 and 17 are both dyed with stinging nettle, said to contain a green dye. In the middle of May, I picked a big dyepot full (and they have no problem stinging through thick garden gloves) and dyed two 25-gram skeins. First skein 16, then skein 17 in the afterbath, followed by modification with a bit of iron. None of the skeins 16 and 17 are green but they work really well along all the other greens. Here they all are, along with an indigo-dyed skein, wound in cakes and ready to knit:

All the green yarn cakes, ready to knit.

I am experimenting with knitting very short scraps of all these colors together, more about that another time. So far, it looks like this:

Norne cut in short scraps and knit – color changes by doubling both the new and the old yarn.

But the search for greens doesn’t stop here. In addition to stinging nettles, May is also full of landscapes covered by wild chervil and broom.

I tried dyeing with common broom last year, but picked the plant too late in the season and got very little color out of it. In their “Dye Plants and Dyeing”, Cannon & Cannon write that flowering stems of broom should be harvested in April or early May. I managed to pick them late in May, which is probably fine since the book is English and most of England is south of Denmark.

On alum mordanted Fenris (pure wool), common broom gives me the greenish-beige that Cannon & Cannon promise. They show an almost black with copper, so I tried modifying with copper water for a few minutes. I have a jar that contains the innards from an old wire in household ammonia, and I just added a bit of it. This gave a very pretty green, which is leaning towards brown.

Wild chervil (also picked in late May) gave the expected fragile yellow with a touch of green. To some eyes nothing special, and for sure, there are many ways to get such tones. But I do find it lovely, it just captures the freshness of spring and early summer. Modified with iron, the color darkens and completely looses the freshness.

Spring Cleaning

In the summer, when all the plants stand tall, I usually collect good bundles of tansy, yarrow, and other wild dye plants. And they have to go before the next harvest.

~

My dyestuff stores from last year contained big bundles of mugwort and tansy, a smaller amount of yarrow, a box full of dry velvet pax, and dry pomegranate shells (among other things).

Spring has shown itself from its worst side this year, but I’ve managed to get outside with my little stove on an extension cord, working to bring down the amount of stored dyestuffs.

First, velvet pax. I found quite a nice harvest of this mushroom last year, more than half of what i found was from driving through a small forest, spotting the mushrooms, and hitting the brake!

I had 190 g of dried mushrooms. On 100 g of wool, that gave a good green (middle skein in photo below) and the afterbath a green-beige (right). I could not capture the color in the photo, but I was pleasantly surprised how well the dried mushrooms retain the color potential, including the green tones. In conclusion, velvet pax is a very good dye mushroom, fresh or dry.

There’s a beige skein on the left in the photo below. That’s 100 g of yarn, dyed with enough dried mugwort to fill a large dye pot completely. I even gave it an iron afterbath. Thinking back, this is actually the second time i get dull beige from dry mugwort, and the conclusion is that it does not dry well. The fresh plant, on the other hand, gives a nice yellow-green.

From left: dried mugwort and iron, dried velvet pax, 1. and 2. bath.

Next up, pomegranate shells. I had saved a very modest amount of shells, from just two fruits, weighing 85 g dry. I followed Jenny Dean’s “Wild Colour” and put the shells in a plastic bag and pounded them with a hammer. To test the new (to me) dyestuff, I wound two 12-gram skeins of Fenris (100% wool) and a small 5-gram skein of Bestla (silk-merino).

The pomegranate shells gave nice yellows on wool and silk. I modified one of the wool skeins with iron, and that gave a darker, greener tone, that actually looks a lot like the color from velvet pax.

Next time people eat pomegranates around here, the shells will be saved. They give a nice color, and they are available during winter, where little else is there in terms of fresh colors.

Several large bundles of yarrow, tansy, and mugwort turned into the yellow-beige first dye for a new round of matrix dyed yarn for Baby Vindauga kits. The second yellow os weld, and the skeins are overdyed with indigo as usual to produce the 9 different blues and greens.

And once I got started, a matrix in purple and blue, using cochineal and indigo, also appeared.

The matrix skeins turned into contrast colors for new Baby Vindauga Kits, you can see them at my Etsy shop:

Germination Test

I harvested seeds from my dye plants last year, for the first time. So instead of just counting on the seeds, I decided to test their germination before spring truly arrives.

~

Last year, I harvested seeds of dyer’s coreopsis and woad from the garden, not a big surprise there. Coreopsis is an annual, and will make huge numbers of small seeds. My woad plants were in their second year, so their seeds were also expected.

The surprise was my Japanese indigo. When I harvested my last plants on October 24th last year, several plants were flowering. On a whim, I potted a plant that I had just ripped out of the soil with roots, and brought the pot inside. There, it calmly kept growing, actually until we went to London for Christmas – the plant had died when we came home. When I was going to throw it, I noticed the seed, good numbers, actually. But it did spend the summer outside with the bees.

Japanese indigo seeds.

I tested the germination of all my dye seeds by placing 10 seeds in moist kitchen paper towel in a ziplock bag that I put under the microwave oven where it’s warm and dark. From January 31st, I let the seeds germinate for a week, and got this result:

Coreopsis, harvested September 27th – 5 out of 10.

Coreopsis, harvested October 24th – 6 out of 10.

Woad – 5 out of 10.

Japanese indigo – 9 out of 10.

Not bad! That was on February 7th, so I decided that this was still too early for the coreopsis. Also, I just sewed it directly last year. So I tossed the sprouted coreopsis for now.

The sprouted woad and japanese indigo, on the other hand, went into seed-starting pots where they now grow. Last year, I found that I was too late in the season, and that was with germination beginning on  April 16th. My notes are sporadic, but it seems they grew in the seed-starting pots for about a month, and in larger pots outside for another month before I transferred them to the garden. So that would have been mid-June.

Various sources disagree on when to start seeds indoors, maybe because they are written for different climates? Recommendations range from early May, 2-3 weeks before the last frost to 6-8 weeks before the last frost.

According to (the authoritative?) “Handbook of Natural Colorants” chapter 7, “Indigo – Agricultural Aspects”, Japanese indigo should germinate inside in April and be transferred to open land in June – and that just happens to be what I did last year (although I hadn’t read that chapter yet). The book goes on to conclude that Japanese is a good crop for Central Europe, but not for England and Finland because the growing season is too short.

I imagine that it’s possible to beat the short season by transferring well grown plants, and doing it earlier than June. So that’s why my sprouted indigo is allowed to continue growing indoors, and more seeds are germinating. Even though this is what it looks like outside:

The frozen wasteland…

The Dye Plants are Sown

Today, I’ve sown some of my dye plant seeds in small pots indoors. The night frost has almost gone, you see…

Last year, I had luck growing Japanese indigo and woad from seeds that I cultivated indoors before planting outside, so I’ll do the same again with Japanese indigo this year. I’m skipping woad because Japanese indigo has a much higher dye content. Also, I have some woad plants growing from last year, so they might flower and produce seeds.

I’m also sowing seeds of weld and madder, and that’s the first time I try those. Weld seeds look like poppy seeds, but the plant is related to cabbage and mustard. It is said to have exceptionally fragrant flowers the second year, so I hope it’ll survive that long!

Madder seeds are a bit special, angular and sticky

Now, all the seeds are in their little pots. Madder seeds just under the surface, weld and Japanese indigo seeds just on the surface.

Planning my Dye Garden

Although I’ve had unsuccessful attempts in the past at growing dye plants myself, I’m determined to try it again this year. But it’s always a good idea with a plan B, and that’s my sister.
Last year, she grew Coreopsis in her garden, and since she is not a dyer herself, she decided to give me the dried plants. I threw them in my dye pot with a 10 g test skein, since the amount of dried plants wasn’t that large
coreopsis

but that was just the first skein of many. In the end, the small amount of plants in the top photo dyed 6 test skeins or 60 g of wool in a range of orange colors.

FACTS – COREOPSIS
Mordant 10% alun
Water Tap
Yarn Supersoft 575 m/100 g
Yarn:Dyestuff ratio about 1:1 dried plant weight, but I could have used less
Conclusion Excellent dyestuff, contains a lot of color

I hope she grows some more this year – after googling around, I found that some types of coreopsis are annuals, some perennials, and some are annuals that self-seed very easily, but I don’t know which one my sister has. So I’m also going to try. So I have ordered these seeds from www.wildcolours.co.uk (they sent the seeds the same day, and they arrived in my mailbox in Denmark in 3 days). It’s woad, japanese indigo, coreopsis, and dyer’s greenweed.
seeds
And this is what I am going to do with them:
  • Japanese indigo – I’ve read in several places that you have to plant the seeds indoors. The timing depends who you ask, anything from 8 to 2 weeks before the last frost (wildcolours say 2-3 weeks). Here in Denmark, 2-3 weeks before the last chance of frost would be the beginning of May, so that’s my plan
  • Woad – I’ve tried planting woad seeds outside in the past and they didn’t grow. The information you can find online is mixed – some people say plant them inside, some say outside. This time, I’ll follow this and plant them outside in March. We’ve moved since I tried it last, and the old garden was in a very windy and cold spot, so maybe it will work this time
  • Coreopsis – this says you can sow the seeds directly in early spring, so that would probably be March-April around here. It also says it likes a South-facing wall
  • Dyer’s greenweed – this says to sow it outside in the fall, but this says you can also do it in February. Since it is now February and my seeds just arrived, I’m just going to try it now. Both sets of instructions agree that you should soak the seeds in warm water overnight or 24 h before planting, so that’s what I am doing. Then plant them outside in pots – they need cold to break dormancy
Jeg har før prøvet at gro farveplanter, uden succes. Men jeg har nydt godt af min søsters høst af skønhedsøje, som farver kraftig orange. I år prøver jeg igen at få noget til at gro: japansk indigo, vajd, skønhedsøje og farve-visse.
