Habitat details as listed in assessment
This perennial shrub species is known to grow in rocky wadis and gravel and sand alluvial plains (El Alqamy 2004, Fawzi and Ksiksi 2012, Mahmoud et al. 2018), however it has also been recorded from disturbed ground near to cultivation sites (Feulner 2011, 2016). It is also considered to be found along roadsides. Typically, it produces small white flowers between January and May (Karim and Dakheel 2006) which are used by various insects, including Cylindrothorax angusticollis suturellus (Gillett and Gillett 1996). Aerva javanica has woody stems and can grow up to 75 - 120 cm in height (Western 1991, Karim and Dakheel 2006).
