'Alma Potschke' is another aster hybrid that blooms late summer into fall, with quarter-sized, bright rosy-pink daisy-like flowers; a great contrast to the typical russets and muted oranges of fall. This is a large aster, growing 3 to 4 feet tall and wide, so give it the room it will need. Use in a perennial border, shrub or foundation border, and with ornamental grasses.
Grow in average, medium to dry, well-drained soils in full sun to part shade. Pinching back stems in late spring will lower overall plant height, but will also delay bloom onset and increase branches, increasing the number of blooms. A light winter mulch will help protect crowns. Cut stems to the ground in early spring before new growth appears. Wet soils in winter can be fatal.
