Here in Connecticut, asters in several pale colors grow wild in just about any uncultivated space, blooming in late summer and early fall. Its name comes from the Greek word meaning “star”. Another of its names is starwort. An amazing number varieties have developed, but where I live, the New England Aster, with small light lavender flowers, is probably the most prevalent. Collecting enough for dyeing small amounts of wool is no problem. Its stems, flowers, and leaves will provide a range of yellow based shades, depending upon mordant:
Alum – Yellow-green
Chrome – Gold, brass
Tin – Yellow-gold
Iron – Grayish green, muted
No mordant – yellow-green, pale
The color of the flower is immaterial for dyeing purposes, so don’t hold out hope for lavender! Aster is poisonous in large doses, but was used in the past for bleeding, lung disorders, dysentery, and malaria. Some Native American tribes smoked the dried root, ate the cooked plant and also brewed a tea from the leaves. Take care not to confuse asters with daisy fleabane, which blossoms earlier. Also beware of bees – the pink New England asters in my garden are abuzz with them. They tend to settle for a while in the yellow center.
This is the treacherous month when autumn days
With summer’s voice come bearing summer’s gifts.
Beguiled, the down-trodden aster lifts
Her head and blooms again.
