– Oxallis (wood sorrels) (flowers) – the one with the yellow flowers. Use the flower heads, some stem ok. It is nearly fluorescent yellow, and quite colorfast on alum mordanted wool.

Usually I do this as an after-bath, once I have the initial colour. Useful for shifting the dye shade, and some good surprises in store!
