Latin Name: Petunia × hybrida ‘Tritunia Ultra’ 

The Petunia ‘Single Grandiflora Tritunia Ultra’ is a high-performance annual celebrated for its massive, weather-resistant blooms and vigorous trailing habit. Growing 6–10 inches (15–25 cm) tall with a spread of 24–36 inches (60–90 cm), it excels in hanging baskets, containers, and ground cover.

This grandiflora-type petunia produces 3.5–4.5 inch (9–11 cm) single flowers in bold shades of pink, purple, blue, and white, often with contrasting veins or star patterns. Part of the Tritunia series, it’s bred for exceptional rain/heat tolerance and continuous flowering from spring to frost without deadheading.

Thrives in full sun and well-draining soil, with moderate drought resistance. Its self-cleaning habit and disease-resistant foliage make it ultra-low-maintenance.

Ideal for landscapes or patio displays, pair with calibrachoa, sweet alyssum, or silver dichondra
