Trumpet creeper, cow itch vine, hummingbird vine
Trumpet creeper, so named for its trumpet-like flowers and creeping habit, is native to (or naturalized in) eastern North America, as well as parts of Europe and a few locations in Latin America. It prefers swamps, riverbanks, forests, and thickets. Trumpet creeper is popular with gardeners, and with ruby-throated hummingbirds.
Plants: Sprawling woody vines form a thick tangle on the ground, or work their way up fences and other supports via aerial rootlets, sometimes reaching 40' (12 m) in height. It spreads by suckering as well as seeding, and is considered invasive in some habitats, notably the southeastern US.
Leaves: Compound, odd pinnate, up to 15" (38 cm) long. Each leaf is shiny and dark above, and dull bluish-green below, comprised of 7 to 10 oblong or elliptic leaflets. Leaflets are 1½-2½" (4-7 cm) long, with serrate edges.
Flowers: Dense clusters of orange-red flowers are trumpet-shaped. Each flower is up to 3" (7.6 cm) long and about 1" (2.5 cm) around. Flowers appear in July.
Fruits: Seed pods resemble pea pods. Each pod is 4-8" (10-20 cm) long, and has two ridges running lengthwise. Seeds are ⅜-¾" (1-2 cm) long, and linear.
Medical: Leaves produce redness and itching in some, but this appears to be rare.
