This species is native to South Africa (Cape Provinces and KwaZulu-Natal).
Crassula perforata is a popular shrubby and sprawling succulent with fleshy, grey-brown stems and grey-green with reddish margins when grown in full sun. It grows up to 2 feet (60 cm) tall. Stems are upright at first but become woody and prostrate over time. Leaves are variable in size and shape. They grow in opposite pairs. Each leaf is triangular, up to 1.4 inches (3.5 cm) long, up to 0.8 inches (2 cm) wide, and more or less fused to the opposite leaf of the pair. Flowers are small, star-shaped, white to pale yellow, and appear in spring.
The specific epithet "perforata (per-for-AY-tuh)" is the feminine form of "perforatus," meaning "pierced" or "penetrated," and refers to the perforated appearance of the leaves. It is the perfect passive participle of the Latin verb "perforo."
How to Grow and Care for Crassula perforata
Light: C. perforata prefers full sun to partial shade. However, intense afternoon sun in the hottest period of summer can burn the leaves of the plant. A place with morning sun and afternoon shade would be perfect. Indoors, place your plants in a window where they receive at least 6 hours of direct sunlight.
Soil: This plant is not particular about soil pH, but it requires very porous soil with excellent drainage. Use commercial potting soil mixes designated for use with succulents or mix your own.
Hardiness: Like most Crassulas, this succulent will tolerate some amount of short-term freezing, but extremes of cold or heat will cause it to lose leaves and die. C. perforata can withstand temperatures as low as 20 to 50 °F (-6.7 to 10 °C), USDA hardiness zones 9a to 11b.
Watering: 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. Potted plants require more frequent watering than those in the ground.
Fertilizing: C. perforata does not need much feeding but will benefit from a small amount of organic fertilizer in mid-spring when it starts actively growing.
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: This succulent is generally started by leaves or stem cuttings. It can also be grown from seeds and offsets. The easiest way is to propagate C. perforata from a single leaf, while using stem cuttings is the fastest way to get a decent-sized plant. These processes are most successful if done at the beginning of its active growth period. Sow the seeds in the spring or summer. Propagating by dividing offsets is very easy because the parent plant has already done most of the work for you.
