Common Milkweed (Asclepias syriaca) ah-SKLEE-pee-us syriaca

Other Names Asclepias syriaca (NGN)
Family Apocynaceae

Milkweed, (genus Asclepias), genus of about 140 species of herbaceous perennial flowering plants belonging to the dogbane family Apocynaceae (formerly in Asclepiadaceae).

Milkweeds are found throughout North and South America, and several are cultivated as ornamentals.

Many milkweed butterflies, including monarch butterflies, rely exclusively on milkweed plants as a food source for their larvae.

These plants contain acrid milky juices that probably make the larvae and their subsequent stages distasteful to predators.

Highlights Best known as a food source for butterflies, this Midwest native perennial is common in fields and open woods. Many butterflies enjoy the nectar, while monarch butterfly caterpillars eat the leaves. Flowers lead to seed pods which split open releasing silky-tailed seeds which are dispersed by the wind.
