Species of ornamental vine originating from the United States (southeastern states). In Poland, it is grown only as a cultivated plant. It grows up to 10 m in length. Thick, weakly twining shoots, but attaching to walls and rocks with numerous adventitious roots. 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 reaching up to 12 cm in length. The capsule is sharply pointed on both sides and compressed along two seams (two carpels), forming distinct edges. The walls are hard and strongly lignified with sparse lenticels in small depressions resembling eyes (the lenticel opening looks like a pupil). The capsule is divided in half by a partition, initially quite thick and fleshy. The seeds are two-part, flat, and wing-like membranous. They are arranged in a row, one after the other, and repeatedly covered by the wings of subsequent seeds. Mature capsules turn brown, dry out, and split open, and the mature seeds are dispersed by wind (in Poland, the trumpet vine is propagated by layering). They germinate after winter, as they require stratification. The presence of fruits has been recorded in Szczecin, Wrocław, Opole, i.e., in the western part of Poland. It is unknown which species pollinate its flowers here (in nature, pollination is primarily done by hummingbirds).

Application: Perfectly suited for cultivation on pergolas, walls, small walls, and other strong supports. It reaches a height of up to 10 m. Trumpet vine is resistant to diseases, pests, and frost. Even if the stems freeze during a harsh winter, new ones quickly grow from the base of the vine in spring.

Flowering: From July to September. Flowers are tubular, 6-9 cm long, and orange in color.

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

Care: The trumpet vine begins its vegetative period relatively late, making it quite frost-resistant. At the beginning of July, leaves intensively develop, forming a green thicket. When fruits (long pods several centimeters long) appear, it is good to remove them to prolong flowering. Each year, between March and April, young shoots are pruned above the 2-3rd node (a pair of buds) above the main shoot. Damaged and weak shoots are cut out completely or only left at the base with a single node. Strong pruning enhances flowering and strengthens the plant's base.
