New York aster ()Symphyotrichum novi-belgii is a native herbaceous perennial that may grow 3 to 5 feet high. It can grow on nutritionally poor soil, in semi-shade or no shade but prefers a sunny location. It is moderately salt tolerant and can grow well in seaside locations  It blooms starting in late summer and persists into early fall with 2-inch light purple to pink flowers with a yellow-orange center.

Like other asters it is a host plant for the Pearl Crescent (Phyciodes tharos) caterpillars and several different moths. Flowers are attractive to bees, including specialized bees, and butterflies. American Goldfinch, Black-Capped Chickadee, Blue Jay, Dark-Eyed Junco, Northern Cardinal, Tufted Titmouse‍, and White-Breasted Nuthatch eat New York Aster seeds, and Ruby-Throated Hummingbird sip the nectar.

It is unpalatable to browsing deer and rabbits.
