Weed Description: A perennial
with slender, twining stems that may reach 10 ft in length. Found throughout the
southeastern United States. Although the name implies a secretion of milky sap as in
other milkweed species (Asclepias spp.), this does not occur in the leaves or stems
of honeyvine milkweed.
Leaves: Opposite, entire,
heart-shaped, 3-7 inches long, 1.5-5 inches wide. Leaves do not have hairs and occur
on petioles that are 1-4 inches long. Leaf surfaces have conspicuous white veins
that arise from a common point (palmate venation).
Roots: Clustered and fibrous.
Stems: Slender, without hairs, twining to 10
Fruit: A smooth, angled
follicle that is 3.55.5 inches long, 1-2.5 inches wide.
Flowers: Small (2-3 mm broad),
white, numerous, and occur on flower stalks that arise between stems and leaves
Identifying Characteristics: A
perennial twining vine with opposite leaves and relatively large fruit (follicle).
This weed is often incorrectly identified as a morningglory (Ipomoea spp.) or Field Bindweed (Convolvulus arvensis).
However, the prominent white veins distinguishes this weed from any of the morningglories,
and the heart-shaped leaf distinguishes this weed from field bindweed.
