This is the start of a plan to grow my own dye plants and some flax for spinning. Woad can get very weedy and is a pest in parts of the USA but it gives such beautiful blues that I'm going to risk it. Actually, it will be lucky to set much seed because I'll be raiding it a lot. The weld is for yellows which are reasonably colour fast and I'm still trying to track down some madder plants. I got a beautiful orangey-red colour from a Eucalyptus nicholi that keeled over during a storm, but the madder red is particularly lovely.
