Trumpet Vine is a climbing, colonizing vine that can reach heights of 40'! It forms a substantial trunk as it matures, easily crushing weak supports. The trunk is greyish with peeling bark which adds winter interest, long after the deciduous leaves have fallen. This vine is best grown on stone walls, dead tree trunks, very sturdy trellises, arbors, fencerows, as screening or anywhere it can be allowed to ramble about. It flowers from the tips of new growth, so heavy pruning to control the shape and size will not effect the show.
For best flowering, it needs plenty of sunlight. The flowers are bright orange to scarlet and up to 3 1/2" long with lipstick tube-shaped buds. Ruby-Throated Hummingbirds and Sphinx Moths are extremely attracted to them and they receive copious amounts of nutrient-rich nectar. Orioles also want in on the nectar, but have to tear up the flowers to access it. The Plebeian Sphinx uses Trumpet Vine as a larval host. The dense foliage also makes for excellent nesting sites for many birds.

Plant Care & Installation Quick-Guide
Proper acclimation and installation are key to your plant's success. Please cross-reference these tips with your plant's specific ID tags:
·
Pre-Planting: Store plants in a light-appropriate area on soil or grass (avoid hot concrete or asphalt) and water daily until the soil is saturated and the pot feels heavy. If temperatures drop below 30°F, move pots to a garage or cover them to prevent root freeze.
·
Installation: Dig a hole matching the depth of the pot, remove the fabric container, and ensure the plant’s crown or root flare is level with the ground. Fill gaps with soil, water heavily, and apply 2 inches of mulch—keeping it clear of the stem.
·
Ongoing Care: Check moisture daily by feeling 1–2 inches into the soil; water deeply at the base if the soil feels dry or warm. Newly installed plants require frequent watering (up to 3–4 times weekly in heat) until fully established, which can take a few months for perennials and up to two years for trees.
