Why the Audubon® Smooth Aster?

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!

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!

How to use in the landscape?

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!

What is the definition of Native?

“In the United States, a native plant is defined as one that was naturally found in a particular area before European colonization. Native plants are the foundation of a region’s biodiversity, providing essential food sources and shelter for birds, especially those threatened by the changing climate. Since native plants are adapted to local precipitation and soil conditions, they generally require less upkeep, therefore helping the environment and saving you time, water, and money.” – The National Audubon Society

How To Plant

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.

How To Fertilize

Incorporate Elements Starter Plant food granular form into the soil when planting. If planting in spring or summer, start fertilizing late fall using Elements Starter Plant food granular form on an annual basis each late fall. Continue this for the first three years to get your plant well established.
