Tecoma stans 'Esperanza' (Yellow Bells 'Esperanza') is a striking deciduous shrub known for its clusters of large, trumpet-shaped, yellow flowers that bloom from April to November. Typically growing 3-6 feet tall in the U.S., it can reach up to 9 feet in more southern regions. Native to South Texas, Arizona, and extending through Mexico to South America, this shrub thrives in well-drained, rocky, limestone, and sandy soils, tolerating both drought and heat. Yellow Bells is a popular choice for rock gardens and perennial borders, attracting hummingbirds, butterflies, and other pollinators. It's moderately deer-resistant and serves as a larval host for the Dogface butterfly.
