Before you choose

Is it a good match for your landscape?

Mature form: Large shrub or graceful small tree
Growing conditions: Full sun to light shade · Limestone or well-drained soils · Low-water landscapes

Allow room for a large shrub or small tree, about 15 feet tall in favorable conditions. A warm, sunny, well-drained location supports its best growth, and young plants benefit from winter protection while establishing.

Acclimation, establishment watering, and arrival care are explained once in the Botanical Scout growing guide →

The personal story

Why I keep growing Mexican Bird of Paradise

Its range and adaptations connect South Texas with Mexico—two landscapes shaped by heat, limestone and alkaline soils, drought, and highly variable rainfall.

Mexican Bird of Paradise grows naturally from extreme South Texas through Mexico. Its clear yellow flower clusters distinguish it from the red-orange flowers of Pride of Barbados and the long red stamens of Desert Bird of Paradise.

I collect seed from older Austin plantings that have persisted with little attention. Some have become genuine small trees. They show what is possible in a favorable site, although age, genetics, and microclimate all influence how a plant performs.
