Tall Flat-topped White Aster Doellingeria umbellata

Previously known as:

  • Aster umbellatus
Description

Flat-Topped White Aster is a native wildflower found in the mountains of NC in moist fields, thickets, and the border of swamps. It can be found from Canada south to FL. The clusters of white composite flowers appear in July-Oct.

This plant prefers a slightly acidic sandy loam that is moist to occasionally wet in full sun to partial shade. Use in groups for best effect around water sites, in naturalized meadows or pollinator gardens. It will naturalize by self-seeding and underground rhizomes.
