Inforescence:
Flowers: Flowers often nodding in a tall, narrow panicle that starts out crowded but elongates with time; white to pinkish; consisting of 5 tiny, often twisting petals attached to a hairy, conical calyx with minute teeth. There are 5 protruding stamens with orange anthers.
Fruits: Fruit an oval capsule with 2 persistent styles.

plant sale text: Beautiful green foliage gives this uncommon southeastern native perennial long-term appeal in the garden. The leaves and flowers of this species bear many fine hairs, hence its common name of Hairy Alumroot. Its dense rosettes of fresh green leaves require at least partial shade to look their best. Each plant grows into a handsome clump as it matures. Stalks of tiny white to pinkish-white bell-shaped flowers are borne on slender stems above the foliage in late summer. In the wild, Hairy Alumroot grows primarily in the mountains from Virginia and Tennessee south to Georgia.
