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 for the ecologically-minded gardener, despite them not being quite as flashy as the cultivated varieties in some cases. Learn more about recommended varieties further down this page.


Asters can be planted in USDA Hardiness Zones 3 to 8 (check your zone here). They come in a variety of heights, ranging from 12 inches to 4 feet, so they work either in the back or front of borders depending on size. They may be tall and stately, or some varieties have a more mounded shape. Asters need full sun, which is at least six hours of direct sunlight per day. With too much shade, they get leggy and floppy. Asters usually bloom for weeks from early to late fall.The most common asters available in North America are the New England aster (Symphyotrichum novae-angliae) and the New York aster (Symphyotrichum novi-belgii). Both of these plants are native to North America and are great flowers for pollinators. We recommend planting a native species of aster over a non-native species when possible, so talk with your local Cooperative Extension or garden center about which species are best suited to your area.

When you think of pretty autumn plants, mums automatically come to mind. But there’s another fall-blooming perennial that your garden needs. Asters, a hardy plant that comes in shades of blue, lavender, pink, and purple, start blooming around the same time as mums when everything else in the garden is looking a little tired and shaggy. “They’re a beautiful alternative or companion to mums,” says Jan Boonstra Pavlinak, horticulturalist and help desk expert with Bluestone Perennials. “They’re pretty easygoing flowers, pollinators love them, and their colors are complementary to many other fall-blooming plants.”Asters (Aster spp.) usually grow as perennial plants. There are many species, however, and about 200 cultivars, with plant heights ranging from a few inches to 12 feet tall. Aster flower colors can be various shades of blue, pink, purple, red, white or yellow. Most of them bloom in the fall but there are some species and cultivars that bloom at other times of the year. There is even one aster that blooms in the winter. With careful selection, there can be asters blooming in your garden year-round. (Source: homeguides.sfgate.com)
