Crassula cotyledonis is a low growing succulent native to South Africa that can reach up to 6 inches (15 cm) tall. Its grey green leaves are flat, rounded, paddle-shaped, grown in rosettes and covered with fine short hairs. The leaves have red or purple margins. The whole leaves can also turn vibrant red when stressed in cold temperatures. From spring to summer, Crassula cotyledonis produces clusters of small cream-yellow tubular flowers from each stem.
Sun Exposure: Full Sun, Sun to Partial Shade, Light Shade. Water: Water thoroughly when soil is dry to the touch, then let drain completely. Avoid letting water sit for too long in the soil to prevent rot and fungal diseases. Reduce watering in the winter. Soil: Porous and well-drained. Optimal pH is around 6.0 (slightly acidic). Temperature: Average summer temperatures from 65ºF/18ºC to 70ºF/21ºC are ideal. In winter, it can survive temperatures as low as 50ºF/10ºC. Fertilizer: Feed with a controlled-release fertilizer at the beginning of the growing season. Propagation: You can propagate Crassula cotyledonis by division, offsets or leaf cuttings. The easiest way is to propagate from a single leaf: put the leaf in a succulent or cacti mix, then cover until it sprouts.
