Description
A semi-evergreen shrub that can grow to a small tree, it features sharply toothed, opposite green leaves that are pinnate unpaired, with 3 to 13 serrate, 8 to 10 cm long leaflets. The leaflets, glabrous on both sides, have an elliptical lanceolate blade 2–10 cm long and 1–4 cm wide, with a long acuminate apex and a wedge-shaped base. The margin is finely toothed It reaches heights of 6 to 9 meters.
The large, showy, golden yellow, trumpet-shaped flowers are in clusters at the branch ends, are bell-shaped-funnel-shaped, five-lobed (with weakly two-lipped), often reddish-veined in the throat and 3.5 to 8.5 cm long. Flowering takes place all year round. The fruits arise from two carpels and are up to 25 cm long, narrow capsules. The flowers attract bees, butterflies, and hummingbirds.[4] The plant produces pods containing yellow seeds with papery wings. They release many seeds with membranous wings when they open. Tecoma stans reproduces sexually (by anemochory) or asexually.
Habitat
Tecoma stans is native to the Americas. It extends from the southern United States through Mexico, Central America, and the Antilles to northern Venezuela, and through the Andes mountain range to northern Argentina. It was introduced in southern Africa, India, and Hawaii.
Yellow trumpetbush is a ruderal species, readily colonizing disturbed, rocky, sandy, and cleared land and occasionally becoming an invasive weed. It thrives in a wide variety of ecosystems, from high altitude temperate forests and tropical deciduous and evergreen forests, to xerophilous scrub and the intertropical littoral. It quickly colonizes disturbed, rocky, sandy, and cleared fields. The species prefers dry and sunny regions of the coast.
Cultivation
Esperanza is drought-tolerant and grows well in warm climates. It is an attractive plant that is cultivated as an ornamental. They are grown in many parts of the world for their beautiful flowering, to adorn streets and gardens. It can be easily propagated by stem cuttings.
Uses
The wood is used in rustic architecture like bahareque, for the construction of furniture and canoes, or as firewood or charcoal. It is a medicinal plant used against diabetes and against diseases of the digestive system, among other uses. The plant is desirable fodder when it grows in fields grazed by livestock. The other name of this plant is Stenolobium Stans, it is also called piliya in urdu. It is a very potent anti-venom against cobra venom, used by Pakistani old medicine. It is proved to be better than anti-sera, the paste of this plant's leaves are applied topically on the cobra bite. Its bio-chemicals bind with the cobra venom enzymes thus effectively inhibiting the venom.[5]
Invasiveness
It has invasive potential and occasionally becomes a weed. The species is considered invasive in Africa (especially South Africa), South America, Asia, Australia and the Pacific Islands. It now presents a significant danger for biodiversity. It competes with local species and can form thick, almost monospecific thickets.
