Symphyotrichum prenanthoides
Symphyotrichum prenanthoides
Crooked-stem aster thrives in partly shaded woodland gardens with consistently moist, humus-rich soil. It requires minimal intervention once established — simply water regularly during dry spells and cut back stems in late autumn. This native wildflower is an excellent choice for naturalized or pollinator-friendly garden borders.
