About

Tecoma stans is a species of flowering perennial shrub in the trumpet vine family, Bignoniaceae, that is native to the Americas. Common names include yellow trumpetbush, yellow bells, yellow elder, ginger Thomas. Tecoma stans is the official flower of the United States Virgin Islands and the floral emblem of The Bahamas.

How to grow it

Tecoma stans is drought-tolerant and grows well in warm climates. It 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. Native to the southwestern United States and adjacent Mexico, Tecoma stans var. angustata is shorter and more tolerant of drought and cold than many of the tropical varieties commonly sold in nurseries.

Where it grows

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. It is evergreen in moist and warmer regions, but is deciduous in more temperate regions that have a pronounced dry season.
