Lampranthus is a fairly large genus with 100 to 150 species native to South Africa. It provides some of the most spectacular bright flowers from the succulent world and is widely used as ground cover, either annual or perennial, as the climate allows. Several species are used for landscaping and vary from shrubby to trailing. All the species tend to become woody as they age.
The generic name "Lampranthus" means "shining flowers" in Latin. The members of this genus have large, highly bright flowers of a range of colors (sometimes even bi-colored) that usually appear in summer and frequently cover the plants entirely. The species typically have long, smooth, elongated, succulent leaves. They can be triangular or cylindrical and appear in opposite pairs on the branches.
The spectacular flowers need full sun. As with most mesemb, they are followed by woody capsules that open when wet to ensure the propagation of the seeds at the best possible time.
Growing Conditions and General Care
Lampranthus plants are generally hardy in USDA plant hardiness zones 8 through 11, but this varies depending on the species. They thrive in well-drained, poor soils and are suitable for soils with a sandy or rocky texture, although they will grow in almost any soil type. These plants 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 spacing 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 of the particular species.
Water the plants immediately after planting, but let the top inch (2.5 cm) of soil dry before watering again. Water your plants in this manner through the first spring and summer they are in place. Once established, they are drought-tolerant and will need watering only during extended dry periods.
Lampranthus plants need full sun to keep the growth from becoming leggy and for best flowering. They do not need fertilizing, as that causes overgrowth of softer, weaker branches. After plants flower, prune off the old flowers and any developing fruits. Lampranthus are short-lived perennials and may need replacement after several years.
For container plants, use a succulent potting mix. Containers need watering throughout the year whenever the top layer of soil dries out. Plants can grow almost year-round in mild climates. Prune as needed at any time of year to keep the plant to size. Bring containers indoors before the first frost is predicted.
Propagation
The propagation is by seed or cuttings. Seeds need warmth to germinate; 60 °F (16 °C) or more is suggested. Cuttings should be taken in summer. A 6-inch (15 cm) shoot stripped of bottom leaves and planted in moist sand should rapidly root.
