Miniature Chin Cactus (Gymnocalycium bruchii) is a tiny low growing cactus native to Argentina. Miniature Chin Cactus blooms in late spring with light pink flowers held over small clustering stems. The plant needs a partially shaded spot protected from the hot afternoon sun. Plant it into a north or east facing rock crevice and don't grow it too dry. Plant it in a well-drained, low fertility soil with other small, slow-growing rock garden plants and succulents.
