Campsis radicans - Trumpet Vine @DBG 19sept05 LAH 215-1APPEARANCE

Tropical vines with huge, brilliantly colored flowers don’t normally grow in Colorado, but Trumpet Vine is an enjoyable exception. A vigorous grower, Trumpet Vine can reach 30 feet, with dark green compound leaves that drop in fall to reveal the vine’s light brown papery bark. From mid-summer to frost, three-inch long vase-shaped flowers of fiery orange-red grow in clusters of four or more. In fall, hundreds of papery seeds develop in five-inch long capsules.

CULTIVATION

Locate Trumpet Vine in full sun in well-drained, amended soil, and water just enough to keep ground slightly moist. Be sure to provide a sturdy support and plenty of room. The vine spreads by underground runners and can become invasive. (This is more of a problem in warmer climates.) Bloom is on new growth; prune while dormant to keep vine manageable. The plants are hardy to -30 degrees.

LANDSCAPE USE

Use this southeast native as a patio cover or to screen an unappealing view. The flowers attract hummingbirds. While not completely deer resistant, Trumpet Vine is not their favorite food.
