Eucalyptus cinerea

Natural range and habitat of Eucalyptus cinerea

Eucalyptus cinerea is native to southeastern Australia, from New South Wales into Victoria.

It grows in open woodland, including grassy and dry woodland, on clay and clay-loam soils from flatter ground and streamside areas to rolling country.

Garden and pot care for Eucalyptus cinerea

• Sun: Give full sun to keep the young growth dense and silver.
• Hardiness: Established plants are hardy to around −15 to −10 °C in a sheltered site. Protect young trees and container roots during severe frost and cold drying wind.
• Water: Potted plants can dry quickly in warm weather, so check them often and water deeply when the top of the mix feels dry. Keep newly planted trees watered during dry spells while they settle in.
• Temperature: Give Eucalyptus cinerea stable conditions around 5–24 °C; move it to a warmer position before temperatures remain under −5 °C.
• Humidity: Average humidity around 40–50% is sufficient for container-grown plants.
• Soil: Well-drained neutral to acidic soil suits garden trees. For pots, use a soil-based mix with added grit or pumice.
• Feeding: Use a moderate dose of balanced houseplant fertiliser while fresh growth is active, then ease off as growth slows.
• Keeping round silver leaves: Shape the plant while it is young. For a new crop of round leaves, make a hard cut after the current shoots have matured and before the next vigorous flush begins.
• Container size: Move to a larger stable pot once the root ball has used most of the current container. Keep the drainage hole clear.

Eucalyptus cinerea warning signs

• Leaves curl, crisp or shed during warm windy weather: Heat and drying wind can dry a potted root ball quickly. Water deeply and check the pot more often during exposed weather.
• Young shoots become long and the silver colour weakens: Low sun or overly rich feeding can produce soft greener growth. Move the plant to a sunnier outdoor position and keep feeding moderate.
• Leaves yellow while a pot remains very wet: Dense wet mix can stress the roots. Replace heavy potting mix and make sure water leaves the container freely.
• Raised lumps or distorted patches develop on leaves: Eucalyptus gall wasp or eucalyptus sucker can cause these changes. Check the affected growth closely and identify the pest before choosing a treatment.

Eucalyptus cinerea is toxic to people and pets

• Keep this plant away from children, cats and dogs that may chew it.
• Its aromatic oils can irritate the mouth and digestive tract and may affect the rest of the body.
• Swallowing plant material may cause drooling, vomiting, stomach pain, weakness or unusual behaviour. Contact a veterinarian or medical professional if symptoms develop.

What does Eucalyptus cinerea mean, and who first published it?

Eucalyptus comes from Greek words meaning “well covered”, a reference to the operculum over each unopened flower bud. The Latin epithet cinerea means ash-grey or ash-coloured.

Charles Louis L'Héritier de Brutelle established the genus Eucalyptus in 1789 in Sertum Anglicum, page 18.

George Bentham first described Eucalyptus cinerea in 1867 in Flora Australiensis, volume 3, page 239; Ferdinand Jacob Heinrich von Mueller had proposed the name.
