Sparklette Tecoma Season-by-Season in Phoenix Spring (Feb–Apr): New growth flushes as nights warm and the first wave of golden-orange trumpets opens. Prime planting window and a good time for a light shape-up. Summer (May–Sep): Peak performance. Sparklette loves the heat and reflected warmth off walls and pavement, blooming hardest through the hottest months. The summer monsoon often triggers an extra flush of flowers. Fall (Oct–Nov): Blooming continues into the cooler weeks. A strong secondary planting window before winter slows growth. Winter (Dec–Jan): Stays evergreen in mild winters but is frost-tender. Expect blooming to pause and tip dieback if temperatures drop below about 28°F. Cover young plants on hard frost nights; mature plants flush back from the base in spring even if cut back by cold.

Sparklette thrives in full sun and reflected heat, in well-drained or caliche soil, anywhere you want compact year-round color on very little water. It is ideal for foundation beds, low borders, pool surrounds, and large containers. It is not the best fit for a cold, frost-prone low spot or a deep-shade location, where bloom and evergreen structure both suffer.
