All the subspecies of E. globulus are notable for the saplings to more than head height, which are conspicuous with large, glaucous juvenile leaves. These can be seen along roadsides or in disturbed areas where the parent trees occur. Coppice growth of similar form can often be seen as new sprouts on upper trunks and branches. Eucalyptus globulus is an important plantation species and has been the subject of several studies (Kirkpatrick 1975, Jordan et al. 1993) which have revealed that subspp. globulus, bicostata and pseudoglobulus intergrade extensively. The natural distribution of subsp. globulus, in Victoria, has undoubtedly been confused by forestry plantings this century.
