Pest Details

Spreading Dogbane
Spreading Dogbane

Origin:

Native to North America, and found throughout the western states, Canada, and into the northeast United States.

Biology:

A perennial plant reproducing from either seeds or rhizomes. It grows in many soil conditions, along roadsides, waste areas, and some crop situations. Like other dogbanes and the closely related milkweeds, this species is toxic to livestock that may eat it.

Identification:

Very similar to Hemp dogbane, but with flowers that are somewhat larger and are a pinkish white color. Mature plants grow to around 2 feet tall, and are extensively branched in the upper part of the plant. Stems are often a reddish color, with leaves opposite along them. Leaves are on short stalks and often assume a drooping pose. They are rounded at the base and more pointed at their apex. Flowers occur in clusters at the end of stalks that arise from the end of each branch. Flowers are pink, bell shaped, and up to 1 inch long. Fruiting bodies, or seed pods, are thin and up to 5 inches long, splitting open to release the silk-tufted seeds into the wind.

Characteristicts Important to Control:

A perennial reproducing from either seeds or rhizomes, and the seeds are likely to be spread long distances by the wind.
