Natural populations

Eucalyptus salubris is widespread in the Avon Wheatbelt and Coolgardie regions of southwest Western Australia, extending from Mullewa in the north to as far east as Laverton and the plains north of Mt Ragged [1,2]. It is usually a small to medium-sized tree 8–15 m. The trunks and upper limbs are usually spirally fluted, particularly in younger trees. The main habitat of E. salubris is on plains or diffuse valleys, growing on sandy loams or clay loams, often in pure stands.

Flowering and seeds

This species flowers during September to December [1,3]. Seed capsules persist on trees until at least the following spring and abundant quantities are often present on this species. There are about 400 viable seeds per gram; seeds start to germinate in about 10 days if grown at 15-20°C with no pretreatment required [3].

Cultivation and uses

Eucalyptus salubris is an attractive, non-lignotuberous tree which has fluted trunks and upper limbs and smooth, copper-coloured bark. It is a highly ornamental eucalypt suitable for cultivation in semi-arid climates on alkaline clay loams [4]. In the past, wood from natural stands of this species was formerly used as firewood and was considered useful for poles, fence posts, minor building construction and mining timber [1]. The grain makes the wood attractive for furniture, craftwood, veneer and recently it has been used to make head joints for flutes. The bark of E. salubris has relatively high tannin content (18-20%) and its flowers produce abundant pollen and honey flow for apiculture [5].
