Yellow Trumpet Flower
Tecoma stans
Easy · Beginner friendlyAbout Yellow Trumpet Flower
Tecoma stans, yellow bells or esperanza, is a fast-growing shrub or small tree native from the southern United States through Mexico and Central America into tropical South America. It carries airy pinnate leaves and clusters of bright yellow tubular flowers from late spring through fall, often nearly year-round in frost-free regions. Heat, drought, and poor soil barely slow it once established, making it a workhorse of arid and semi-arid landscapes. Hummingbirds and butterflies visit the nectar-rich flowers. Traditional uses in Latin America include leaf and bark preparations associated with blood-sugar management, a topic that has drawn pharmacological research, but the plant's landscape value is color and resilience. It is the official flower of the U.S. Virgin Islands and Oahu.

History
Tecoma stans, yellow bells or esperanza, is native from the southwestern United States through Mexico and Central America into tropical and subtropical South America. Its trumpet-shaped yellow flowers make it a signature heat-loving shrub for dry landscapes, especially in Arizona, New Mexico, Texas, and northern Mexico. The Spanish common name esperanza means hope, a fitting label for a plant that flowers through heat and drought.
Indigenous and traditional medicine systems used the root bark and leaves for diuretic and anti-diabetic remedies, and modern pharmacological studies have investigated hypoglycemic compounds in the leaves. In cultivation, compact forms such as 'Gold Star' made it a low-maintenance xeric garden staple, while in some disturbed tropical areas it has escaped and behaves as a weed. It is also the official flower of the United States Virgin Islands.
