Rhubarb Root

This turned out to be one of the most staining dyestuffs that I've come across to date. The colour I obtained from my dye bath was rather like that of turmeric, a yellowish brown, but still brown! Maybe when I try again with some fresh young leaves later in the season, I'll obtain shades of green? From the left, mordanted with alum, copper, alum and tin, and alum and iron.
