Symphyotrichum novae-angliae ‘Purple Dome’
Description
A cultivar of the Nebraska native New England Aster, “Purple Dome” is covered with purple flowers in early fall. Pinch back at least once before July for better branching and more compact plants (plants will flop if left untouched). Pinching will also slightly delay flowering to extend the appeal longer into fall.Photo courtesy of Gardenworld, Inc.For reference only:
