When placed in a south-facing window, the interlocking leaves will grow close, tight, and compact light green leaves. While plants growing in areas with less light will be more soft and open.

Flowering and Fragrance

The watch chain crassula is a small shrub with slim zipper-like stems. It has compact, tree-like branching, and the leaves are placed in tiny rows opposite each other.

There are many variations to the typical watch chain species. Some look like a cockscomb, while others have a red or brownish-yellow tint.

It also comes with silver stripes and grows like a corkscrew. However, the main variety remains the most attractive with its simple and beautiful greenish-white flowers.

When growing Crassula muscosa (Crassula lycopodioides) indoors, it is unlikely to bloom.

However, in certain conditions, small, pale yellowish-green, musty-smelling flowers may appear along with the delicate interlocking leaves on the branching stems during spring to mid-summer.
