A botanical illustration of C. laeve

Cynanchum laeve (syn. Ampelamus albidus) is a vining perennial herb native to eastern and central U.S. states and Ontario. Common names include honeyvine, honeyvine milkweed, bluevine milkweed, climbing milkweed, and smooth swallow-wort.

Like bindweed and some other members of the Convolvulaceae, Cynanchum laeve is a twining vine with heart-shaped leaves common in roadsides, fence rows, fields, and disturbed areas. However, C. laeve is easily recognized as a member of the Milkweed family by its opposite leave placement, milky sap and distinctive flowers and "milkweed pods." The seeds are wind dispersed and can travel long distances.[1]

Cynanchum laeve is considered a noxious weed in several states,[2] and can be very difficult to eradicate from fields because of its deep, extensive root system.[3] Like many other milkweed species, C. laeve contains toxic cardenolide alkaloids,[4] and is a food plant for the caterpillars of Monarch butterflies.[5]
