The species varies throughout Australia in the colour of both juvenile and adult leaves, shape of the operculum and associated staminal flexion, and in its ability to survive in a variety of well-watered and seasonally arid sites. Seven subspecies are currently recognised to accommodate this variation (see McDonald et al. 2009), with only the type subspecies in Victoria (but also see notes under Eucalyptus aff. camaldulensis (Torrumbarry), E. ×studleyensis, and E. ×oxypoma).
It is the most widely planted eucalypt outside Australia.
