It is thought to be a foodplant for a subspecies of the Desert Blacktip, Elphinstonia carlona amseli (Gillett 1997). This dwarf shrub species has been reported from abandoned fields, gravel plains and slopes within low mountain habitats (Western 1991, Jongbloed et al. 2003, Mahmoud et al. 2018). This is an annual species, although sometimes perennial, which can grow up to 50 cm in height (Jongbloed et al. 2003). It has fleshy, oval-shaped leaves with toothed edges, in addition to yellow flowers which are present between February and May (Jongbloed et al. 2003). Diplotaxis harra has been recorded as flowering regularly and profusely within its first season while still surviving for long periods (Batanouny 2001). This plant also has hairs which help to absorb moisture when conditions are humid (Batanouny 2001). It is also a crop wild relative of Brassica species, which includes cabbage, mustard, rapeseed and turnip, among others (Kameswara Rao 2013).
