Susanne Grosjean, of the Wednesday Spinners group in Downeast Maine, says, “You need only three dye plants: indigo for blue, madder for red and weld for yellow. Three primary colors, all excellent color-fast dye plants.”
Coreopsis tinctoria Open pollinated. Beautiful native ornamental. Provides a full palette of color from yellows and greens to rusts and browns-and even black.
Persicaria tinctoria Open pollinated. Japanese indigo preferred by dyers in Maine. A tender annual, indigo thrives in fertile soil and likes heat and humidity.
Rubia tinctorum Open pollinated. Ancient and excellent source of red dye. Harvest roots after three years and grind to yield a wash- and light-fast red dye par excellence. 4' plants.
Saponaria officinalis Open pollinated. Not a dye plant; saponin-rich roots and leaves used to gently wash wool. Sweetly clove-scented pink perennial attracts pollinators. 3' plant.
Alchemilla mollis Open pollinated. Perennial. 12-18" Bears large loose sprays of tiny greenish-yellow flowers from early summer onward. Makes a good border and ground cover in shady locations.
Helianthus annuus (90-100 days) Open pollinated. Rare indigenous heirloom used as a natural dye source for coloring baskets purplish charcoal. Also edible. 8' stalks.
