Why gardeners choose this variety
Colorful Sun Series Double Yellow Portulaca Grandiflora, commonly called moss rose, is a hardy succulent annual prized for dense fully double golden-yellow blossoms and incredible heat hardiness. Each bloom holds layers of soft ruffled yellow petals that form compact rose-like flower heads, fully unfurling under strong sunlight and curling inward at sunset or on overcast days. Fine, fleshy needle-shaped green leaves form low trailing mats that hold water reserves, letting this portulaca thrive in dry, blazing hot conditions where most ornamental flowers wilt. As a member of the premium Colorful Sun line, this strain delivers consistent bright yellow double blooms with little color variation across all seedlings.
This double yellow moss rose is a go-to low-care flower for bright, dry outdoor spaces. Its trailing stems spill gracefully from hanging baskets and patio pots, fill gaps in rock gardens, and create vivid golden edging along sunny walkways. It pairs beautifully with red, orange, and pink portulaca varieties to craft warm, eye-catching mixed plant displays. Blooms persist nonstop from late spring until the first light fall frost with minimal watering needed. Tiny native bees visit its open flower centers, adding subtle pollinator activity to water-conserving, sun-drenched landscape designs.
