Characteristics:

Flytrap dogbane is an attractive perennial wildflower with freely branched stems from 20-50 cm high. The herbage ranges from glabrous to tomentose. The leaves are opposite on the stems and are oblong-elliptic, ovate, oval or cordate-ovate in shape. They range from 2.5-7 cm long.

The inflorescence is a terminal to axillary cyme with pink flowers. The flowers are narrowly bell-shaped and 5-7 mm long with erect to spreading lobes. The calyx lobes are ovate with rounded tips or lanceolate with pointed tips, measuring 1.5-3.5 mm long. The fruits are narrow follicles, measuring from 5-14 cm long, and held erect or reflexed.

Flytrap dogbane is an excellent nectar source for butterflies. The plants are often covered with a wide variety of butterflies and other insects, which are often so busy that one may setup and take decent photos without them flying off.


Habitat:

Flytrap dogbane may be found on dry, open or lightly wooded slopes and along disturbed roadsides from the valleys and foothills to medium elevation in the mountains.


Range:

Flytrap dogbane may be found across much of Canada and the United States except the southeastern US.
