It would be good in containers or hanging baskets as it scampers over the edge of pots. It is very fast growing, covers quickly and is ideal for small gardens and retaining walls. This is the larval host plant for the Tailed Black-eye butterfly. Named from the Latin ‘crassus’= and ‘ula’= diminutive referring to the fleshy succulent leaves.
