This species has lost >75% of its habitat to urban and agricultural expansion, and habitat loss continues. Subpopulations on small remnants are threatened by competition from unmanaged alien invasive plants, overgrazing, and inappropriate fire management.

Recent field observations indicate that this species persists at 14 locations. There are 10 subpopulations, the largest is on the Tygerberg and consists of 500-700 plants. Other subpopulations are much smaller, consisting of between 10 and 100 plants, and all are isolated, and therefore the population is considered severely fragmented. The population continues to decline due to ongoing habitat loss and degradation.
