Additional Information about Aster novae-angliae 'Purple Dome'

This compact and floriferous aster cultivar, Symphyotrichum novae-angliae ‘Purple Dome’, is covered in deep purple blooms in late fall. From Dr. Dick Lighty, former Director of the Mt. Cuba Center, the habit of Purple Dome aster is symmetrically mounded and reaches only 2’ tall with a maximum spread of 3 feet. The foliage is fuzzy, narrow, and densely covering, providing a solid backdrop in your garden until the show begins in late fall. It is attention grabbing when planted enmasse!

Originally occurring in moist prairies, meadows, thickets, low valleys and stream banks throughout the eastern United States, Symphyotrichum novae-angliae grows in full sun in average to moist soil. New England aster can go through short dry periods and prefers good drainage.

Aster species are a staple in plantings with the intention of erosion control and pollinator habitat. For best practices in highly managed settings, cut back after flowering to prevent the spread of variable seedlings.
