Eucalyptus gregsoniana is well established in cultivation and freely available in commerce. Although a smallish mallee in the wild it can become much larger in cultivation, where the lignotuber is also produced. At Logan there are trees from 1989 that are now 8–9 m tall, and others from 1990–1991 that are 6–7 m. They tend to branch low down forming large heavy limbs, clad in attractive pale grey bark that peels in irregular patches. In older, unshed areas the bark is reddish brown. Young stems are yellowish to orange-red and bear falcate leaves of typical eucalyptus grey-green when mature, although they flush red. Flowering starts when the tree is quite young, and can be very prolific. Eucalyptus gregsoniana can be regarded as a substitute E. pauciflora for small gardens, where its pale bark and abundant flowering will make it an attractive feature. It is slightly less hardy than E. pauciflora, but for most purposes in the United Kingdom (at least) it can be regarded as hardy at the present time; it also has the advantage of tolerating some lime in the soil (Gum Group 2007).
