Culture
An annual, Moss Rose Portulaca ‘Grandiflora Mix’ is 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 last frost date or start indoors 6-8 weeks earlier. Set out seedlings and purchased plants at last frost date. Plants may self-seed. Moss Rose Portulaca ‘Grandiflora Mix’ features a bright combination of flowers amidst its green trailing foliage and it blooms repeatedly all summer long.
Noteworthy Characteristics
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.
Problems
No serious insect or disease problems. Watch for aphids. Crown rot may occur in poorly-drained soils.
Garden Uses
Good for poor dry soils where many other plants struggle. Edging or ground cover for beds, rock gardens or along walks. Containers, hanging baskets. Sprawl over stone walls.
