Distribution and ecology
Widespread in arid areas, extending from central-western W.A. through southern N.T. and S.A. to south-western Qld and north-western N.S.W.
Commonly associated with ranges, occurring in deep gravelly soils of dry creek lines, rarely on rocky slopes.
Part of the S. esuriale group of subgen. Leptostemonum (Bean 2004).
Ripe fruit reported to be toxic to stressed sheep and cattle in Qld and N.S.W. See for example www.weeds.mangrovemountain.net/data/Solanum%20sturtianum%20-%20Thargomindah%20nightshade.pdf
A distinctive narrow leaved form of this species occurs along the northern margin of its distribution in W.A. This was earlier named S. morrisonii Domin but it is still questionable whether this form should be distinguished.
