Tecoma stans Gold Star was selected by noted Texas horticulturist, Greg Grant, from a garden in San Antonio, TX. It's intermediate between the west Texas Tecoma stans angustata and the tropical Tecoma stans stans. Unlike either of its parents or other Tecoma stans subspecies, Gold Star blooms when very young and never stops until cold weather hits. Sun-poof golden yellow flower clusters are so plentiful that they often weigh down branchlets. The sweet fragrance, while not perfuming a whole neighborhood, is strong enough to be noticeable when walking past.

It makes a fine container annual in the north given sun and heat, and becomes a 15' tall multi-stemmed tree where temperatures don't drop much below freezing. A few nights of 25° knocked a 12+' tree right to the roots, but by the following May it was 4' tall and pumping out blooms.

Requirements are few: sun, heat, well-drained soil in the neutral to alkaline range. It's pest resistant too. Best and longest flowering occurs if the prolific seed pods are removed (bees are wild about this plant). Some gardeners report self-seeding; others have never seen a seedling. As this is a hybrid, the seeds would not come true.

All in all, an almost perfect plant.
