Campsis radicans (Bignonia radicans)

Share on

Common Name: Trumpet Creeper, Trumpet Vine

Full sun to light shade; medium to moderately dry moisture level; tolerant of a wide range of soils including coarse sands and gravels, sandy loams to fine silt loams, heavy silts, silty clay loams and stiff clays; slightly acid to neutral pH.

6-40 feet height depending on support (30-40 feet common) by 4-10 feet width; large, reddish orange, fluorescent, trumpet-shaped flowers 2-3 inches long; blooms June through September; 3-5 inch brown seed pods, each containing numerous seeds and each seed having two transparent wings.

Growth Rate:  Very fast, growing 10 or more feet in a season

Maintenance:  Low maintenance, long-lived vine.  Infrequent disease or insect problems.  Flowers come from the tips of new growth so blooming is not affected by pruning in early spring.  Suckers profusely from underground roots and freely self-seeds which can make it weedy; will form impenetrable colonies.  Pruning is an important means of controlling this vine in smaller gardens.  Best to train 1-2 main stems up a sturdy support and then every winter cut all the long shoots back to within 6 inches of these main stems.  Occasional stem die-back to the ground can occur in severe winters.

Propagation:  Seed germination code C(60) at 41 degrees F. or fall sown.  Easy from seed.  Moderately easy from stem or root cuttings.

Native Region:  Statewide

Vine climbs by aerial rootlets and requires sturdy support due to its considerable weight.  Foliage grows well in shade but plants need good sun for best flowering. Up to 24 cultivars available including pure red and pure yellow flowers.  Has long, deep underground runners so it is difficult to transplant.  Attracts hummingbirds, butterflies and bees.
