Crassula perforata is a small shrubby and sprawling succulent, up to 18 inches (45 cm) tall. The stem is erect, fleshy, later prostrate and woody. Short, broad ovate, opposite, gray-green leaves edged in pink color with small whitish or pink dots on the margin, up to 0.8 inch (2 cm) long and up to 0.5 inch (13 mm) wide. The flowers are very small, star-shaped and white in color.
Light: Full sun to partial shade. Most needs some shade in the hottest part of summer, but require bright light to attain their most vibrant color.
Water: As succulents, they don’t need frequent watering, since they store it in their leaves. If they are left to sit in wet soil, their roots will rot. During cooler months, give them a good drenching and then allow the soil to dry out, before watering again. They go dormant when the temperature gets hot in summer and need even less water.
Temperature: Prefers average summer temps (65ºF/18ºC – 70ºF/21ºC). In winter, cool to 50ºF/10ºC.
Soil: A well-drained succulent mix, with an ideal pH around 6.0 (slightly acidic).
Fertilizer: Many people underfeed their succulents during the growing season. Feed with a controlled-release fertilizer in the beginning of the season or weekly with a weak liquid solution. Use a balanced 20-20-20 fertilizer at 1/4 strength on mature plants, and a fertilizer with less nitrogen on young plants.
