Crassula muscosa, also known as Crassula lycopodioides, is a sparingly to densely branched succulent with erect to decumbent stems. It grows up to 10 inches (25 cm) tall, and it is very variable in size and leaf shape. Branches often curve towards the light. The main branches are woody and up to 0.4 inches (1 cm) in diameter. Tiny leaves are light green or grey- to brownish-green and densely packed around the stem, forming a square mass. Flowers are cup-shaped and pale yellowish-green to brown.

USDA hardiness zones 9a to 10b: from 20 °F (−6.7 °C) to 40 °F (+4.4 °C).

How to Grow and Care

Plant in well-drained soil in full sun to light shade or indoors. If planting indoors, place in a room that gets a lot of sunlight, such as near a southern-facing window. The best color is maintained with a little shade, even on the coast.

Watch Chain has typical watering needs for a succulent. It is best to use the "soak and dry" method and allow the soil to dry out completely between waterings.

Since Watch Chain is not cold hardy, it should be brought indoors when the temperature falls below 20 °F (-6.7 °C).

During the growing season, the plants should be fed with a controlled-release fertilizer. They can be fed weekly with a weak liquid solution.

While in summer, it needs a lot more water, and it should not be exposed to full sun, as it only values brightness but would suffer under excessive sunlight. When these conditions are not met, the plant begins to dry and stiffen, generally starting from the stem's base up to tips.
