Crassula — 25 species

Crassula is a Southern African succulent genus best known for the Jade Plant (C. ovata) alongside compact curiosities like String of Buttons (C. perforata), Watch Chain Plant (C. muscosa), and Campfire Crassula (C. capitella 'Campfire'). All thrive in bright light — ideally four or more hours of direct sun — in fast-draining, gritty soil watered on a strict soak-and-dry cycle that prevents root rot. All Crassula species are toxic to cats and dogs; ingestion can cause vomiting, depression, and incoordination. Keep every member of this genus well out of reach of pets.
