Description Aster cordifolius ‘Avondale’, now known scientifically as Symphyotrichum cordifolium, is an eastern North American native wood aster that is a prolific bloomer carpeting the shade garden with light blue flowers on arching stems in early fall when little else blooms and the hostas are in decline. The small light blue to lavender blue flowers have lemon yellow centres that age to red. They are produced in abundance creating a beautiful and long-lasting filler in the garden or in autumn flower arrangements! Tolerant of dry shade. Can also be grown in sunny conditions with even moisture where plants will be more upright.
