Features: This is a desirable plant because of its ability to attract a wide variety of pollinators such as butterflies, hummingbirds, and bees. It has 3-4” trumpet shaped flowers that grow in clusters. It has red-orange flowers, as well as a yellow cultivar10. Trumpet vine is easy to establish and can be used to decorate landscapes beautifully if managed properly.

Siting: Strategic siting is necessary to successfully maintain Trumpet Vine. Trumpet Vine uses aerial rootlets to spread which can cause damage to wood, brick, and stone10,12. It is recommended that you site this plant on a structure such as a vinyl decorative archway or somewhere that pruning will not be a problem, as you will have to control the plants aggressive growth12. This plant is drought tolerant and blooms best in full sunlight10.

Care: For transplanting, plant crown at soil level18. At planting, water the roots and surrounding area slowly and deeply. Keep soil moist until plant is established, then apply enough water to thoroughly moisten the root zone when the soil is dry or during drought. Modify water recommendations to reflect site drainage and rainfall. Apply 3” of mulch over the planted area. Do not allow mulch to touch the plant stems18. You may also propagate by cuttings, seeds, or semi-hardwood cuttings10.

Pests: Deer resistant, no serious pest issues5,10,12,19.

Cautions*: The sap of this plant can cause skin irritation on contact10,12.
