Portulaca grandiflora. Easy to grow, Moss Roses prefer to be direct-sown in full to partial sunlight in a sandy, well-draining spot in the garden after the last frost date, by just pressing the seeds lightly into the soil, as light is needed for germination. Or raise as transplants 6 to 8 weeks before transplanting out after threat of frost has passed. Use individual peat pots or seed-starting cells to avoid root disturbance. Provide even moisture and strong light. Harden off the seedlings by gradually acclimating them to the outdoors over 1 to 2 weeks before transplanting out. Once seedlings are 2" tall, thin or transplant 12" to 24" apart. Moss Roses, when established, love heat, blazing sun, and dry soil, making them perfect for sun-baked patio containers. Summer flowering. Height: 3" to 6".
