Intro: Trailing to weakly climbing, herbaceous perennial vine found in dry longleaf and pine-oak forests and woodlands.
Stems: Stems may be many from a single rootstalk, prostrate or trailing and with spreading or close-pressed hairs.
Leaves: Leaves alternate; petiolate; divided into 3 slightly leathery, elliptic to lance-shaped leaflets, each 3/4-1 1/2 in. long and smooth or hairy.
Inforescence:
Flowers: Flowers in short racemes of 1-6 from leaf axils, dark pink or pink and white, about 1/2 in. long, bilaterally symmetric and with typical pea-flower shape, including a large, reflexed banner petal.
Fruits: Fruit a hairy, narrowly oblong pod.
Comments: This is the larval host plant for Long-tailed Skipper, Gray Hairstreak and Zarucco Duskywing butterflies.
Height: to 10 ft. long
plant sale text: Eastern Milkpea is a delicate twining vine in the pea family (Fabaceae) that has charming ¾" bright pink flowers. It can be found in open, dry woodlands throughout the southeastern U.S., and it will weakly twine up other vegetation or creep along the ground. Similar to Spurred Butterfly Pea, Eastern Milkpea is a tough little plant that is drought tolerant once established. This species is a larval host plant for the Long-tailed Skipper, Gray Hairstreak, and Zarucco Duskywing butterflies.
