How to Grow and Care

Lampranthus are generally hardy in U.S. Department of Agriculture plant hardiness zones 8 through 11, but this varies depending on the species.

Lampranthus thrive in well-drained, poor soils and are suitable for soils with a sandy or rocky texture, although they'll grow in almost any soil type. They tolerate exposure to salt and grow in coastal conditions. Plant rooted cuttings in spring after the possibility of frost has passed. Space the cuttings 6 to 24 inches (15 to 60 cm) apart for trailing species, using closer spacings for quicker coverage. Dig a hole just a little larger than the roots at the cutting's base. Put the roots in the hole, cover them with soil and tamp the soil firmly in place. For erect or mounding species, space them according to the mature dimensions for the particular species.

Water the plants immediately after planting, but then let the top inch of soil dry before watering again. Water the plants in this manner through the first spring and summer they are in place. They are drought-tolerant once established, when they will need watering only during extended dry periods… – See more at: How to Grow and Care for Lampranthus.
