Asters are daisy-like perennials with starry-shaped flower heads that range in color from white to blue to purple. They bring delightful beauty to the garden in late summer and autumn, when many of our summer blooms may be fading. Here’s how to grow asters in your garden!
There are quite a few species and varieties of asters out there! The two most commonly encountered asters in the home gardening world are the New England aster (Symphyotrichum novae-angliae) and the New York aster (S. novi-belgii), but you will see a range of hybrid varieties available in showy pinks, blues, and purples at garden centers. “Wild type” species native to your region may also be available and are generally a wise choice ecologically speaking, despite not being as flashy as the cultivated varieties. Learn more about recommended varieties further down this page.
Asters also attract bees and butterflies, providing the pollinators with an important late-season supply of nectar. Thanks to the aster’s late bloom time, they are sometimes called “Michaelmas daisies,” which refers to the holiday of the same name that occurs annually on September 29.
The plant is versatile and can be used in many places—borders, rock gardens, or wildflower gardens, to name a few. Depending on the variety, the plant’s height can range from 8 inches to 8 feet, so you should be able to find one suitable for your garden.
