Eucalyptus torquata (Coral Gum) – A small upright evergreen tree to 15 to 20 feet tall by as wide with persistent gray-brown bark on the trunk and larger branches and with pale blue-green leathery 4- to 6-inch-long leaves. Masses of beautiful flowers appear throughout the year but primarily late spring through fall with orange barrel-shaped buds that have a corrugated base and with horned caps that lift of to expose coral red stamens with yellow tips.

Plant in full to part sun in well-drained soil and irrigate occasionally to infrequently - a drought tolerant species in coastal California gardens that is cold hardy to short duration temperatures down to around 17°F. This very attractive tree tolerates heat, wind, and moderate frost.

Eucalyptus torquata is native to hillsides around Kalgoorlie and Coolgardie in the Goldfields region of Western Australia where it grows in stony loam, clay loam and red sandy soils. The name for the genus comes from the Greek words 'eu' meaning "well" and 'kalypto' meaning 'to cover' as with a lid and an allusion to the united calyx-lobes and petals that is called an operculum that forms a lid or cap that is shed when the flowers open. The specific epithet is from the Latin word 'torquatus' which means "adorned with a neck chain or collar" in reference to the corrugated base of the buds and fruit. It is also called Coolgardie gum for the location it was first described from in 1897, Christmas Tree, for the flowers that appear in December in Australia and Goldfields Red Flowering Gum for mining operations near its native habitat.

It was first introduced in the US by the USDA's Bureau of Plant Industry (BPI) in 1936 (BPI 104163-1936). We first listed this plant in our 1981 catalog and are growing it again thanks to Jo O'Connell at Australian Native Plant Nursery, who produced a nice seedling crop for us in 2021.

The information displayed on this page about Eucalyptus torquata is based on our research conducted about this plant from books in our nursery library as well as from information that is provided by reliable online resources. We also have included our own observations made about it as it grew in the nursery gardens and other gardens visited, as well how the crops of this plant performed in the containers when we had them in our nursery field. We also include comments received from others and welcome hearing from anyone who has information about this plant, particularly if it includes cultural information aiding others to better grow it.

 
We closed for regular business at the end of 2025 in order for the property to be developed for affordable housing.
Our gates remain closed but we will open them by appointment to interested parties through August 21st to liquidate remaining plants, supplies and equipment.
The plants remaining in the field are listed on our
Live Inventory Page.
