About

Aster glehnii is a perennial that grows in clumps and can reach heights of up to 1.5 meters. This species is uncommon in gardens and features slender, dark stems adorned with densely packed, small dark green leaves. In the fall, it produces abundant clusters of petite white flowers with yellow centers, which later develop into seed heads that create a frothy appearance. This plant is particularly valuable for attracting bees during the late flowering season.
