Family

Asteraceae

Botanical Name

AMPELASTER carolinianus

Plant Common Name

Climbing Aster

General Description

Climbing aster is so named for its very long, arching stems which mingle among neighboring shrubs and other vegetation for support. Native to coastal regions of the southeastern United States, this woody subshrub is found naturally at the edges of swamps and wet woods. It is grown in gardens for its showy, late-season display of fragrant, lavender-pink flowers.

The rambling, branched stems of climbing aster are covered with light gray fuzz. They may reach as much as 12 feet (4 meters) in length, and do not die back to the ground in winter. Pointed, medium green, oblong leaves are borne alternately along the stems. Large panicles of pale purple, yellow-centered daisies appear in late summer to early autumn, and are pollinated by bees, butterflies and other insects.

For best performance, provide climbing aster with full to part sun and rich, moist soil. Its stems may be tied to a trellis, or allowed to scramble among roses, shrubs and sturdy perennials. This unique perennial is a great source of fall color for mixed borders or wildflower gardens, and its blossoms make fine, long-lasting cut flowers.
