Portulaca, also known as Moss Rose and even Purslane, is a low-growing, heat-loving annual known for its vibrant, semi-double blooms in shades of pink, yellow, red, orange, and white. This fast-spreading groundcover thrives in hot, dry conditions, making it an excellent choice for Texas landscapes, rock gardens, and container plantings. Blooming from spring through fall, it provides continuous color with minimal care.

This Portulaca variety prefers full sun and well-draining soil, tolerating both acidic and alkaline conditions. It is exceptionally drought-tolerant, requiring only occasional watering once established. The succulent-like foliage helps retain moisture, making it ideal for xeriscaping and areas with poor soil. It is deer-resistant and attracts pollinators like butterflies.

Reaching a mature size of 6-8 inches tall and spreading up to 12-18 inches wide, Portulaca is perfect for mass plantings, edging, and filling in gaps between stepping stones. When planting in clusters, space plants 10-12 inches apart to allow for full coverage. While not known for reliable reseeding, it may self-sow in warm climates.

As an annual in USDA Zones 2-11, it thrives throughout the warm season but does not survive hard frosts. In cooler regions, it can be grown in containers and overwintered indoors if desired. No winter care is needed for replanting in spring.
