Texan gardeners looking for a splash of island‑style color can try the “Sparkle Party” mixed‑container recipe highlighted by horticulturist Norman Winter. The combination of award‑winning Supertunia petunias and Superbena verbena delivers a bright, tropical feel that works well in Texas’ warm summer zones.

What makes Sparkle Party special

The recipe centers on three standout varieties: Supertunia Pink Tiara, Supertunia Saffron Finch and Superbena Violet Ice. Each has earned top honors from university horticulture programs across the country, from Oklahoma State to the University of Florida, and even a Canadian award for the Pink Tiara. The verbena has been recognized by the North Carolina State University JC Raulston Arboretum with multiple “Leader of the Pack” honors.

Choosing containers and soil

Winter recommends a container at least 14 inches in diameter to give the plants room to spread and to provide depth for proper drainage. A container with drainage holes is essential; if the pot lacks them, plan to add a layer of gravel at the bottom.

For soil, look for a lightweight, fluffy mix that feels like it was sold by the pound rather than the cubic yard. The mix should include controlled‑release granular fertilizer, which helps feed the plants over time without the need for constant top‑dressing.

Watering and feeding in Texas zones

In USDA zone 8 areas of Texas, containers often need hand watering, especially during hot, dry spells. Frequent watering can leach nutrients, so Winter suggests applying a water‑soluble fertilizer every two to three weeks, or using a premium granular fertilizer that releases nutrients as you water.

Even during an unusually rainy season—Winter experienced two stretches of twelve straight days of rain—his Sparkle Party plants continued to thrive, demonstrating the resilience of these varieties.

Putting the recipe to work locally

Winter first fell in love with Sparkle Party at Young’s Plant Farm in Auburn, Alabama, but the same vibrant colors can be recreated in Texas backyards. He also uses a larger container version that adds Supertunia Mini Vista Plum Veined and Supertunia Vista Cool Jazz, paired with a “thriller” plant such as Graceful Grasses Queen Tut papyrus for height and texture.

Gardeners are encouraged to plant the mix now for a fall display, as the colors hold up well into cooler months.
