I take no credit for planting the occasional surprise of native Symphyotrichum ericoides (heath aster) in our gardens…they just appear and often in just the right spot. Unobtrusive all summer, but a delightful accent when flowers form in mid-September, Heath Aster presents 1-2′ stems bearing hundreds of tiny white daisies with yellow centers, creating a frothy foam in both sunny and even somewhat shady areas.
There are selected forms out there….‘Snow Flurry’ stays quite low at 6-8″ with 2′ branches that hug the earth, making it a useful native ground cover for the edge of a border or in the rock garden. A new selection ‘Bridal Veil’, introduced by the Chicago Botanic Garden, is believed to be a naturally occurring cross of ericoides and “?”. It produces strong 2′ arching stems with copious amounts of blossoms and forms vigorous clumps.
All forms of Heath Aster prefer well-drained soil and are quite drought tolerant once established. As I mentioned we’ve had plants pop up in even shady situations, but I think you get more flower power with full sun. Deer resistant and pollinator-friendly and hardy in zones 5-8…yay!
