I sent a note to Julia the Ethnobotanist asking what local plant around here I could use for a yellow dye for wool or cotton. Just to see what she said. Mind you, I don't actually have anything to dye at the moment.
She said that I should pick some off the ground and soak them. Several species around here make good yellow dyes. But of course, she didn't have her dye notebook at hand to give me more specifics.
This woman is a walking encyclopedia of plant uses. I might just have to build an extra cabin on the homestead so as to house her and her husband while I pick their brains about wild mushrooms.
