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.
