Yellow dominates in the dye bed at this time of year. Tansy, goldenrod, dyer's chamomile and tormentil (which actually produces a red dye if you use the roots). This season I've been admiring the plants in full bloom more often than using them for dye. It's been a different experience and as some of these were grown from seed this year gives them a chance to get properly established.
(Although today I harvested a handful of chamomile flowers and steeped them in boiling water to quickly dye a skein of silk - the vibrancy of the shade is too good to miss).
