Crassula grisea – Succulent plants
Crassula grisea is an attractive, ornamental, perennial succulent plant with erect stems that grows up to 30 cm tall when flowering. The leaves are tiny, opposite, cylindrical, with rounded or pointed tips and tapering bases. The decussate arrangement of leaves on the brittle stems might be pretty much ordinary and pronounced on different plants. Leaf shading might be bright yellow with a faint greenish tinge, but leaves may also be pale grey, blue-grey or greenish. There may either be a finely velvety or a glabrous surface on the leaves. Each inflorescence, growing on a solitary hairy stalk that emerges from a stem-top, consists of a dense cluster of small flowers. There may be several on one plant. The petals form a bell-shaped corolla for the individual bloom.

How to grow and maintain Crassula grisea:
It thrives best in bright light with some direct sunlight. A sunny windowsill will be an ideal position for these plants. They will not flower without sunlight and inadequate light will cause developing spindly growth.
It grows well in well-drained soil with a neutral pH. Add coconut coir and Pine bark to make the soil more drainage friendly.
Water regularly, during the growing season (April to September), but water sparingly when dormant (autumn and winter). Allow the top of the soil to slightly dry out before watering again.
It prefers ideal room temperatures of around 60°F – 75°F / 15.5°C – 24°C. During winter no less than 50°F / 10°C. Cold weather and damp weather is not good. It loses its color and turns yellow and mushy.
Fertilize every two weeks during the growing season, from spring through summer with a balanced liquid fertilizer diluted by half. Do not fertilize during the winter.
Re-pot in spring when the plant becomes root bound or the soil needs renewing. A good solid and heavy pot is best to use because of these plants are well known for being top-heavy. A heavy pot will prevent them from tipping over.
It can be easily propagated by stem cuttings, leaf cuttings or by basal offsets. The cuttings or offsets should be taken in spring. Take 2-3 inch long stem cuttings and plant it in a 2-3 inch pot of equal parts mixture of peat moss and sand and keep it at normal room temperature in the bright filtered light.
Pests and Diseases:
It has is no serious pest or disease problems. But they are susceptible to mealy bugs, aphids, and fungal diseases. Overwatering may cause the roots to rot.
