A bountiful, breathtaking Spirit that’s smothered in soft lavender-blue blossoms each fall! Smooth Aster’s cheery flowers attract countless bees, butterflies, and other pollinators to your garden. At the same time, the foliage feeds many types of caterpillars and other insects, which in turn sustain bug-eating birds such as wrens and warblers. And, its seeds serve as a late-season treat for sparrows, juncos, and finches; in rural areas, Ruffed Grouse and turkeys may partake as well. You’d want this wonderful native in your garden purely for the beauty of its flowers, but in fact, Smooth Aster offers so much more!

May Benefit & Attract: Wood warblers, finches, sparrows, juncos, wrens, grouse, and turkeys.

The Story

There are many, many species of Asters found around the world. They play important roles in the ecosystems they inhabit, providing substance to insects, birds, and small mammals. Quite a few Aster species are native to North America, like this one. Smooth Aster brightens prairies, open woods, and country roadsides over much of the U.S. and into Canada. Often found in rocky sites, it appreciates good drainage and is fairly drought tolerant once established. You really can’t go wrong with native Asters in the wildlife-friendly garden, and Smooth Aster is one of the best!

The Details

Smooth Aster is one Aster species that is preferred as a host plant by the Pearl Crescent butterfly. This sweet little orange, black, and cream butterfly is a familiar sight in the garden whenever its favorite plants are around!

How to Grow

Smooth Aster will look its best when a few simple practices are followed. First, be sure to plant it in full sun, in an open space with good air flow, and water it well during dry spells. These things will keep leaf diseases like powdery mildew at bay. Second, cut plants down by half when they reach one to two feet tall. This will produce a bushier plant that is less apt to flop later on. And finally, divide your Asters in spring if performance starts to decline. Just dig up chunks and replant, discarding any weak or woody sections. Cut spend plants to the ground in late winter or early spring.
