Perennial asters (Asteraceae) are the star of the autumn garden. In fact aster is the Latin word for star.
There are 180 to 250 species of aster annuals, biennials, perennials, and sub-shrubs.
New England asters are easy to grow. You may notice that their flowers close at night.
This one is our native Smooth Aster Symphyotrichum leave var. laeve.
Most asters used for cut flowers are hybrids of two North American natives:
Aster novi-belgii (New York aster) and Aster novae-angliae (New England aster).
Because there are so many varieties, their names are used interchangeably. Check catalogs, online sellers and tags for height and growing preferences.
