It is a perennial evergreen species which is present throughout spring and summer (Sturt and Stuart 1998, Fawzi and Ksiksi 2012). The lower stems of the plant are woody while the younger stems are bright green (Jongbloed et al. 2003). Round fruit is produced by the plant and it flowers between November to April (Jongbloed et al. 2003). Euphorbia larica is a characteristic species of rocky and stony slopes within the high Hajar Mountains, showing resistance to drought stress and acting as an indicator species for east-facing montane slopes (El-Kablway et al. 2016). It makes use of shallow, spreading roots which capture rain easily (Feulner 2016).
