Coreopsis

(Coreopsis tinctoria)

Coreopsis can provide dyes in maroon, brown, orange and deep yellow. Sow seeds in late winter and transplant when around 5cm tall. Plant in a sunny spot. The flowers, which are used for dyeing, will start to appear 10-12 weeks later. Acids added to the dye will bring out yellows, while alkaline additions will bring out deeper reddish hues.
