Sub-category: Aster family
It is a herbaceous perennial plant growing to 1.5 to 3 m tall with opposite leaves on the lower part of the stem becoming alternate higher up. The leaves have a rough, hairy texture and the larger leaves on the lower stem are broad ovoid-acute and can be up to 30 cm long and the higher leaves smaller and narrower. The flowers are yellow, produced in capitate flowerheads which are 5 to 10 cm in diameter, with 10 to 20 ray florets. The tubers are elongated and uneven, typically 7.5 to 10 cm long and 3 to 5 cm thick, and vaguely resembling ginger root, with a crisp texture when raw. They vary in color from pale brown to white, red or purple.
It is most commonly found in Connecticut in flower gardens and as a crop in farms.
