Honeyvine milkweed
 

Honeyvine milkweed has opposite, smooth leaves that are heart-shaped and lack serration. Although other milkweeds contain a milky latex sap, honeyvine milkweed does not. The weed's leaves can easily be confused with those of moringglories and bindweeds; however, morningglories and bindweeds have alternate leaves. Honeyvine milkweed cotyledons are oval-shaped, while those of morningglories are butterfly- shaped. Another distinguishing vegetative feature of honeyvine milkweed is its long petioles. Its flowers are produced in small, greenish white clusters. One of the plant's most obvious features is its fruit, an angle-shaped pod that may reach a length of 6 inches. When the fruit ripens and opens, it releases flattened seeds, which are windassisted with attached silky, white hairs. The plant may also regenerate vegetatively from its rhizome system.

Honeyvine milkweed is common throughout most of Missouri and is problematic along fencerows and minimum-tillage cropping sites.
