More About Portulaca Color Blast® Double Guava

Portulaca Color Blast® Double Guava is prized for its full, double flowers that resemble miniature roses and bring a lush look to hot, sunny plantings. The warm guava-pink blooms open wide in bright sun and hold their color through extreme heat, delivering high visual impact throughout the summer.

This variety spreads quickly to create a dense carpet of foliage and flowers, making it especially effective in containers, baskets, and ground-level plantings. With minimal water and care, it provides continuous flowering from late spring through frost.

Why We Like It (Our Trials)

In our trials, Color Blast® Double Guava stood out for its vigorous growth, heavy flowering, and strong performance in intense summer conditions. Even in lean soil and high heat, plants remained full and floriferous, making it a dependable choice for gardeners seeking bold, low-maintenance summer color.

Color Blast® Double Guava vs. Other Portulaca Varieties

Color Blast® Double Guava is distinguished by its full, double blooms and lush appearance, giving it a richer, more textured look than many other portulaca selections. Against Color Blast® Plumberry, Double Guava offers a brighter, warmer color palette and similarly vigorous spreading habit, while Plumberry leans into deeper, jewel-toned purples for dramatic effect.

Compared to the Pazzaz® Series (like Pazzaz® Mega Dark Pink and Pazzaz® Mega Red), which emphasize large single blooms and strong upright performance in beds, Double Guava’s double flowers create a softer, more layered display that’s especially effective in containers and hanging baskets.For gardeners seeking rich, double blooms and a trailing habit that excels in baskets, containers, and mass plantings, Color Blast® Double Guava is a standout choice.
