Portulaca grandiflora is commonly called moss rose, which is quite descriptive of this plant’s key ornamental features: ruffled, rose-like flowers (to 1” diameter) appearing on prostrate to slightly ascending stems that form a moss-like foliage mat. This annual is a succulent that typically grows to 6-8” tall and spreads to 12” wide or more. Flowers bloom summer to frost and come in single, semi-double or double forms in colors including red, rose, orange, yellow, white, and pastel shades thereof. Flowers do not open on cloudy or rainy days. Cylindrical, fleshy, medium green leaves (to 1” long) appear in clusters along reddish stems.
Planting & Caring –
Easily grown in poor to average, dry to moderately moist, well-drained soils in full sun. Drought tolerant. Sow seed directly in the garden after the last frost date, or start indoors 6-8 weeks earlier. Set out seedlings and purchased plants at the last frost date. Plants may self-seed.
