According to the SANBI Red List Assessment, this species is of Least Concern as it is range-restricted but not thought to be threatened (von Staden, 2014). This taxon is highly desirable and sought after and has become rare due to over-collecting and other threats (Vlok & Raimondo, 2012). This species and several others of this genus were among those targeted and confiscated from illegal plant collecting (Confiscation Lists (2016-2021) provided by Karoo Desert Botanic Garden, Kirstenbosch Botanical Garden and Cape Nature). Subpopulations have been systematically cleared out for horticultural and traditional medicine purposes, causing overall population decline (Molteno. S, personal communication 2022, 15 June).This suggests that this genus and species is being targeted and that this species is at risk of over-exploitation.

This taxon has an extent of occurrence of 5832 km² (von Staden, 2014). It is currently widespread but subpopulations are morphologically distinct making them vulnerable to population loss (Molteno. S, personal communication 2022, 15 June).
Whole individuals and subpopulations are removed from the wild.
Low. The plants are slow-growing and long-lived, while the germination rate in habitat is low on average and seedlings have a high mortality rate. Moreover, this species does not form seed banks; the seeds being viable for a year or two at most.
The seeds are wind-dispersed, but to a very moderate degree, as the seeds generally do not travel more than a few meters from the parent plant. Individual subpopulations that are geographically separated to any degree are therefore vulnerable; Should they die out or be removed, they are unlikely to be re-established from surrounding subpopulations.
A number of subpopulations are small and extremely isolated geographically. Should any of these subpopulations die out, their chance of being re-established, without human intervention, is effectively zero.
