Nebraska Growing Notes:
‘Alma Potschke’ is a cultivar of the native New England Aster, bringing its trademark vigor and late-season bloom to Nebraska gardens. It thrives in full sun and tolerates clay soils, making it well-suited for much of the state.
This cultivar is notable for its intense magenta flowers, which stand out even in autumn landscapes. Like many asters, it benefits from occasional watering during extended dry periods and may require staking or pinching back in early summer to control height and encourage bushier growth.
It provides crucial nectar and pollen for Monarchs and other migrating butterflies, as well as native bees, at a time when many other plants have finished blooming.
Landscape Use:
Ideal for pollinator gardens, native borders, cottage gardens, and fall-focused displays. Pairs beautifully with goldenrods (Solidago), ornamental grasses, Echinacea, and Liatris. Its vivid pink flowers offer a striking contrast against autumn yellows and purples.
Caution:
Non-toxic and wildlife-friendly. Foliage may develop powdery mildew late in the season, though it is less noticeable in garden settings and does not significantly impact blooms. Can self-seed modestly in open soil.
