Natural dyeing – Lupine

It seems like greens are difficult to get with natural plant dyes, so when I read that green (even bright acid green!) could be obtained with Lupine flowers, I wanted to try it.

We have had lupine growing in our backyard for years – the flowers seem to be a favourite of bees, and they are a dramatic, beautiful, colourful flower. I read on The Easy Blues that lupine is originally a North American plant, though I remember being in Vantta, Finland and seeing vast fields full of them… they self-seed, and the seed pods POP sending the seeds all over the place, so apparently there they’re almost treated like a very pretty weed.

So.. this definitely isn’t a Viking Age dye plant, and not medieval for Europe either, but I’ll add them to the category with Avocado – fun to dye with… and free!

Lupine flowers

In the spring I started a number of lupine plants in seed starters and got them into pots once it was safe to so so. Unfortunately… either the squirrels or magpies had other ideas, and more than half of them went…missing. The established plants from previous years returned though, and by the time they went to flower in early/mid June, the new plants were WAY behind. I was concerned that the flowers I had would go to seed before the new flowers came in, so I ended up picking some of the purple flower heads (along with two pink ones too)   in mid-June, and put them in a paper bag to dry.

Since the bees seem to love these flowers, I didn’t pick everything; I left a few of the flower heads for the bees.

Finally in late July I picked two more (and put six more in a bin to collect the seeds, as they’d already lost their flowers) and filled my dyepot with water from my rain barrel.  I hope that next year I have more plants that flower… and although I think I’d get better colour from fresh flowers, will likely have to collect the dried ones as they bloom fully, and be more alert to catch them before they go to seed.

I brought the pot with the flowers (on the stem, but no leaves) and rainwater to just below a boil for half an hour, and then let it lightly simmer for another half-hour. From there I extracted the plant material, and let the dye liquor cool a little.

I had only put in enough water to cover the flowers, so there wasn’t a lot of dye liquor. I hadn’t weighed the flowers either (since most were dry and two were fresh, so it wouldn’t be useful for future anyways) but I didn’t feel like I had a lot of dye. I put one skein of handspun Romney wool two ply yarn into the dye pot, but there was too little liquid.

The handspun Romney wool yarn was pre-mordanted a few days earlier with Alum. I wanted this to be as green as possible, so I didn’t want to shift the colour too much towards yellow by using wool mordanted with the oak galls I had experimented with earlier.

Mason jar instead

Instead, I transferred the (still warm) dye liquor and my yarn into a mason jar, and put it in my (black) dye pot in the sun in my backyard. I wasn’t too hopeful – the dye liquor was sort of an amber brown colour… what I had read online indicated it would be a rich aubergine – so I thought perhaps I didn’t have anywhere near enough flowers.

However… when the wool went in, the colour appeared on the yarn… sort of a muddy brown to start, but then shifting to a sage green. I rotated it every half hour for about two hours, and then rinsed it (with a little vinegar). I found very little dye came out of the yarn, and the resulting shade was a lovely sage green!

While the first skein hung to dry outside in the shade, I put another skein into the mason jar. This steeped for about 4 hours, but the day was cooling off as well. This came out a fair bit lighter – more of a light celery green.

Maybe for next year

I found out that in spring, the lupine leaves are also great for getting green – in particular the acid green I really was enthusiastic about. I planted more lupine plants in my garden this summer as well, so hopefully next summer they’ll come back bushy so I can safely harvest some leaves!

    What a lovely colour! I didn’t do any lupine dyeing this year, but spring is definitely the best time for fibrant colours. Thats when you get almost neon green. I resently found out that you can get blue out of lupine flowers, I want to try that next year!

      I heard that spring is good for that neon – and that it’s not just the flowers but the leaves too. I didn’t do any natural dyeing this summer, but maybe next year. I harvested a BUNCH of seeds last year and planted some new plants this year – but they were too small to cut up for dyeing – hopefully next summer they come back and will give me good dyestuffs 🙂

    It seems you can dye with pretty much anything these days. I saw lots of lupins in Argentina in the Andes. They grow like a weed on the side of the road. I think they were brought over by Europeans. I haven’t had much luck growing them in my garden because of the snails and slugs. Maybe England is too wet! You got a nice color there, very natural. I have heard people adding their work to baking soda bath to get brighter colors, have you tried that?

    • Dawn says:

      There are lots of different modifiers, but I haven’t tried that with Lupine yet. When I was doing this dyeing, I was mostly trying to work with all materials I could find or make -rather than as much purchased stuff.

    This is Lovely! Here in Nova Scotia, Lupines abound everywhere, in abandoned yard, in ditches, on field edges and of course in gardens. I will have to gather some next spring to experiment with as well.

    • Dawn says:

      OH that sounds lovely! I think they’re gorgeous flowers, and such interesting leaves too. I’d love to see yards full of them… (If there were many abandoned lots around here I might seed-bomb them with lupine.. LOL)
