'Gold Star' Esperanza is a selection I made from a private garden in San Antonio. It was introduced by Lone Star Growers. 'Gold Star' was selected because it was the earliest blooming Tecoma stans that I trialed. Previously, Esperanza was difficult to sell as it didn't produce blooms in the container until late in the season. 'Gold Star' actually produced them as a liner.
Tecoma stans requires bright light and warm temperatures. It is propagated by softwood cuttings under mist. Bottom heat is recommended. I generally use a 3,000 ppm IBA quick dip to promote better rooting.
This particular selection is intermediate between the West Texas Tecoma stans angustata and the tropical Tecoma stans stans. Flower and leaf size is intermediate between the two.
Although grown as a shrub and a perennial in San Antonio, South Texas, and Mexico, Esperanza works best in the nursery trade as a tropical container plant, similar to Hibiscus, Bougainvillea, and Mandevilla. It isgenerally sold in one gallon or three gallon containers.
Esperanza has relatively few pests. In the greenhouse, it can be attacked by spider mites and aphids. Outdoors it is generally pest free. Too keep the plants tidy and continuously blooming in the landscape, it is recommended that the clusters of seed pods ("green beans") be cut off.
All selections of Tecoma stans are uniquely adapted to hot sunny Texas summers. 'Gold Star' provides a more marketable plant however.
