Natural populations

Natural occurrences of this species are restricted to coastal and subcoastal parts of southern Western Australia, including offshore islands near Esperance such as Mondrain and Middle Islands [1,2]. On the mainland populations are usually found within 50 km of the coast. Eucalyptus utilis is a non-lignotuberous, relatively short-lived eucalypt, up to 8 m tall. Natural populations grow in the vicinity of low-lying areas on alkaline sands, sandy clays or sandy loams, derived from limestone or alluvia [1]. This species was formerly known as E. platypus var. heterophylla [1,2].

Flowering and seeds

Eucalyptus utilis flowers during December to January [1,3]. Seed capsules persist on trees until at least the following summer. There are about 220 viable seeds per gram; seeds start to germinate in about 7 days if grown at 15-20°C with no pretreatment required [3].

Cultivation and uses

Eucalyptus utilis is a fast growing, small tree which under cultivation it develops a spreading and densely foliaged crown. The relatively small stature of this species makes it an ideal urban shade or amenity tree in areas where large trees pose problems. It grows extremely well on near coastal sites that have alkaline, sandy soils. On favourable sites it establishes rapidly and has excellent potential to provide a windbreak or sheltbelt for stock on rural properties [1], particularly in areas where strong coastal winds are prevalent. It is considered salt tolerant [4].
