Crassula Dubia, commonly known as the Crassula Ivory Towers, is a perennial succulent native to the Eastern Cape of South Africa. This succulent belongs to the Crassulaceae family and is appreciated for its striking architectural structure. 

Overview and Characteristics

Crassula Dubia features tall, slender stems that grow upright and form a cluster of geometrically arranged branches.

The stems of Crassula Dubia display a fascinating color gradient, transitioning from light green at the base to shades of ivory, cream, or pale yellow at the top. The leaves are small and scale-like, densely arranged along the stems, and can take on a slightly triangular shape. As the plant matures, it develops a woody base, adding to its appeal.

Care Tips

  • Lighting: Crassula Dubia thrives in bright, indirect light. Place it near a window with filtered sunlight or in an area with ample natural light. Avoid exposing it to direct, intense sunlight as it may cause sunburn.
  • Temperature and Humidity: This succulent prefers moderate temperatures ranging between 60°F and 75°F (15°C and 24°C). It can tolerate higher temperatures, but protection from extreme heat is recommended. Crassula Dubia adapts well to average household humidity levels.
  • Watering: Crassula Dubia has low water requirements, like most succulents. Ensure the soil is allowed to dry thoroughly between each watering session. Water thoroughly but infrequently, ensuring excess water drains away to prevent root rot.
  • Soil and Potting: Plant Crassula Dubia in a well-draining succulent or cactus soil mix. It should be formulated to provide excellent drainage. A mixture of potting soil, coarse sand, and perlite works well for this succulent.
  • Propagation: Crassula Dubia can be propagated through stem cuttings. Allow the cuttings to dry and callus for a few days before placing them in well-draining soil. Provide indirect light and avoid overwatering until new roots develop.
