|Where the New England aster (Aster novae-angliae) is hairy, this clump-forming, rhizomatous perennial is hairless. From late summer to mid-fall, the cultivar 'White Ladies' bears corymb-like panicles of large, wide, white flowerheads with bright yellow disk florets. Foliage is deep green. This aster does best in sun or part shade where soil is moist, fertile, and well-cultivated. Grows to 4 feet tall and spreads to 3 feet. Divide every second or third year. To encourage bushy growth, cut back by 1/2 in late spring or early summer. Native to eastern North America.
