Fairy Crassula

Fairy crassula is a low, mat-forming succulent with paired rounded green leaves and clouds of small star-shaped flowers. [SANBI](https://pza.sanbi.org/crassula-multicava) describes growth to about 30 cm in sheltered shade or partial shade. Leaves are darker in shade, and plants can expand quickly in favorable conditions. Provide a sheltered, mild site and compost-enriched soil. It suits a shaded container or rock garden where its spreading growth can be managed. Prune overgrown mats and propagate from cuttings or seed. Leaves, plantlets and stem pieces can establish new plants, so dispose of unwanted growth carefully. [Australian government weed guidance](https://keyserver.lucidcentral.org/weeds/data/media/Html/crassula_multicava_subsp._multicava.htm) records environmental weed behavior for the typical subspecies. Local suitability and containment matter; the county fire category does not override those concerns. The [San Luis Obispo County January 2014 plant list](https://www.slocounty.ca.gov/departments/planning-building/forms-documents/environmental-forms-and-documents/plants-information/county-approved-plant-list) explicitly names Crassula multicava in its Crassula notes and assigns F2. This source category identifies its most fire-retardant plants for the 30–70-foot band from a structure. It is not a guarantee against burning. The county conditions the rating on suitable soil moisture, avoiding crowding, removing dead material, separated planting groups and preventing ground-to-canopy fuel connections. The rating belongs to the named identity, without extending it to other species or cultivars.
