Crassula ammophila Toelken
This species is native to South Africa (Northern Cape and Western Cape).
Crassula ammophila is a sparingly branched succulent shrub with brittle branches and fleshy, grey-green to greyish-brown leaves, all densely covered with coarse recurved hairs. It grows up to 32 inches (80 cm) tall, sometimes climbing into the surrounding vegetation. Leaves are opposite, inversely lance-shaped, with the upper face flat to slightly convex, and convex lower face. They are up to 0.6 inches (1.5 cm) long and up to 0.15 inches (0.4 cm) wide. Flowers are tubular, cream-colored, and appear in spring in globular heads on short, hairy stems.
The specific epithet "ammophila" derives from the Greek words "ámmos," meaning "sand" and "philos," meaning "beloved or loving," and refers to the natural environment of the species that grows in scrub vegetation of the coastal sandveld.
How to Grow and Care for Crassula ammophila
Light: Crassulas prefer full sun to partial shade. However, intense afternoon sun in the hottest period of summer can burn the leaves of the plants. Most Crassulas can be grown indoors if given enough light. Place your C. ammophila in a southern window where it receives at least 6 hours of direct sunlight.
Soil: These succulents are not particular about soil pH, but they require very porous soil with excellent drainage. Use commercial potting soil mixes designated for use with succulents or mix your own.
Hardiness: Most Crassulas will tolerate some amount of short-term freezing, but extremes of cold or heat will cause them to lose leaves and die. C. ammophila can withstand temperatures as low as 30 to 50 °F (-1.1 to 10 °C), USDA hardiness zones 10a to 11b.
Watering: This plant has typical watering needs for succulents. Avoid overwatering by using the "soak and dry" method, where the soil is soaked with water, slowly drained, and left to dry out before watering again. Reduce watering in winter.
Fertilizing: Crassulas are slow-growing succulents and do not need much feeding. C. ammophila will benefit from a small amount of organic fertilizer in mid-spring.
Repotting: Repot as needed, preferably in spring, at the beginning of the period of active growth. Make sure the soil is dry before you begin repotting.
Propagation: Crassulas are generally started by leaves or stem cuttings. They can also be grown from seeds and offsets. The fastest way to get decent-sized C. ammophila is to grow it from stem cuttings. Propagating Crassulas with offsets is very easy because the parent plant has already done most of the work for you. Sow the seeds in spring or summer.
