A species of ornamental climbing plant originating from the United States (southeastern states). In Poland, it is only cultivated as a plant. It grows up to 10 m in length. The thick, weakly twining stems, however, attach to walls and rocks using numerous adventitious roots. The leaves are large, up to 30 cm, odd-pinnate, serrated, and dark green. The fruit, although strongly resembling young bean pods, is actually a capsule that reaches up to 12 cm in length. The capsule is sharply pointed at both ends and compressed along two seams (two carpels), forming distinct edges. The walls are hard and strongly woody with rare lenticels in small depressions resembling eyes (the lenticel opening is like a pupil). The capsule is divided in half by a septum, initially thick and fleshy. The seeds are two-parted, flat, and winged. They are arranged in a row, one after another, and repeatedly covered by the wings of the successive seeds. Mature capsules turn brown, dry, and split, and the mature seeds are dispersed by the wind (in Poland, the plant propagates by layering). They germinate after winter, as they require stratification. The presence of fruit has been recorded in Szczecin, Wrocław, Opole, thus in the western part of Poland. It is unknown which species is responsible for pollinating the flowers (in nature, pollination is mainly carried out by hummingbirds).

Application: It is ideal for cultivation near pergolas, walls, fences, and other strong supports. It grows up to 10 m in height. The trumpet vine is resistant to diseases, pests, and frost. Even if the stems freeze in harsh winters, new growth will quickly emerge from the base of the vine in spring.

Blooming: From July to September. The flowers are fused-petal, trumpet-shaped, 6-9 cm long, and orange in color.

Requirements: Requires a sunny position, well-drained soil with a neutral, slightly acidic, or slightly alkaline pH.

Care: The trumpet vine starts its vegetative period relatively late, making it quite frost-resistant. In early July, the leaves rapidly develop, forming a green bush. When the fruits (long, several-centimeter pods) appear, it is advisable to remove them to extend blooming. Every year, around March or April, cut back the young stems above the 2-3rd node (a couple of buds) above the main stem. Damaged and weak stems should be completely removed or only one node should be left at the base. Strong pruning enhances blooming and strengthens the base of the plant.
