Crassula multicava is a perennial, evergreen, creeping, succulent plant that is a native of South Africa. It is a moderate to fast-growing, mat-forming plant that grows to a height >30 cm. It is found usually in eastern coastal areas of New Zealand.
The star-shaped, pale pink flowers are small and appear in large clusters above the leaves. No seeds are produced in New Zealand but small plantlets develop in these clusters and drop off to form new plants.
The leaves (4×4 cm) are fleshy, sometimes with tinted red margins and are pitted with small hydathodes (open water stoma), which serve for rapid absorption of water from the leaf surface.
Though Crassula multicava flowers it doesn't set seed in New Zealand. It does form small plantlets which fall to the ground and grow into new plants. 

Crassula multicava is listed as a pest by New Zealand's Biosecurity Accord. It spreads easily by small fragments and competes with native species.

The fleshy leaves are covered with small hydathodes (a modified pore,
 which exudes drops of water).
