Lighten up your late-season garden with Smooth Blue Asters. This robust native species features soft periwinkle blooms with an extended bloom season - even flowering past frost. The late-season blooms are an important food source for butterflies and bees and spent flowers provide seeds for birds. Star-like flowers and smooth green foliage are a lovely addition to the late-summer garden. This perennial will harmonize beautifully with other flowers in your meadowscape. (Symphotrichum laeve)
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low
temperatures; the lower the zone number the colder the winter.
If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will
survive the winter temperatures in your area.
If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack
of freezing winter temperatures do not provide a time for winter dormancy (rest).
Smooth Blue Aster is a hard-working wildflower with a wide native range across Eastern and Central North America. The long-lasting flowers feature soft blue petals that radiate from golden centers, which turn reddish later in the season. It is a butterfly magnet and a larval host for striking Pearl Crescent and Silvery Checkerspot butterflies. Happiest in a full-sun to part-sun spot and almost any soil type, Asters just need room to grow. This is an excellent choice for meadowscaping and natural garden design. Lovely lavender-blue flowers harmonize beautifully with Purple Coneflowers, Goldenrod, and Black Eyed Susans.
