More About Portulaca Color Blast® Plumberry

Portulaca Color Blast® Plumberry stands out for its rich, jewel-toned purple blooms that add depth and drama to hot, sunny plantings. The flowers open fully in bright sunlight and maintain strong color even during intense summer heat, making this variety a standout in high-exposure areas.

Its trailing, spreading habit allows it to fill containers and ground-level spaces quickly, creating a dense mat of foliage and flowers. With minimal water and maintenance, Plumberry delivers continuous, high-impact color from late spring through frost.

Why We Like It (Our Trials)

In our trials, Color Blast® Plumberry impressed with its fast coverage, heavy flowering, and outstanding heat performance. Plants remained lush and colorful even in lean soil and high temperatures, making it a dependable choice for gardeners who want bold summer color with minimal effort.

Color Blast® Plumberry vs. Other Portulaca Varieties

Color Blast® Plumberry sets itself apart with deep, jewel-toned purple blooms and a vigorous trailing habit that quickly fills sunny beds, containers, and hanging baskets with rich color. Against its Color Blast® counterpart Double Guava, Plumberry leans into darker, cooler tones, giving it a bolder look that pairs beautifully with warm-toned companions or contrasting foliage. While Double Guava emphasizes lush, double flowers, Plumberry focuses on rich pigmentation and dependable ground-level coverage.

Compared to the Pazzaz® Series—such as Pazzaz® Mega Red and Pazzaz® Nano Tropical Punch—it offers a more dramatic color statement and stronger trailing performance, whereas the Pazzaz® Mega selections are bred for larger single blooms and the Nano is ideal for compact spaces and tidy edges. For gardeners seeking intense purple hues and a free-spreading habit that shines in mixed containers and sunny borders, Color Blast® Plumberry is a versatile and eye-catching choice.
