It produces small red-brown flowers between February - April and September - October (Jongbloed et al. 2003, Karim and Dakheel 2006). It grows in sand and gravel plains, in addition to disturbed areas (Jongbloed et al. 2003, Feulner 2011, 2016), and is classed as a xerophyte (Jongbloed et al. 2003, Böer and Saenger 2006).

Assessment rationale/justification
This species was previously assessed as Least Concern, and it is known to occur in at least one protected area. Although it may be badly grazed, it is unknown to what extent this currently impacts the population. Pergularia tomentosa can also persist in disturbed areas which may increase its resistance to development and land use change. Therefore, it is assessed as Least Concern.
