Site Selection


Portulaca is a succulent annual that prefers full sun and well-drained soil. Tolerates heat and drought. Does well in containers.




Does best when direct-seeded outdoors once the danger of frost has passed. Sow seeds on the soil surface and press lightly to settle. Seed can also be started indoors 6-8 weeks before the last frost and transplanted outdoors after the last frost. Take care to not disturb roots when transplanting. Optimum soil temperature for germination is 70-85˚F. Seeds will sprout in 10-14 days.
