DescriptionThis fast growing species can reach around 15 metres. It is often multi stemmed trunked which is crooked or straggly. It has smooth, white and grey or grey brown bark which sheds in large plates or flakes. Adult leaves are 7–12 cm long, 1.5–3.5 cm wide, and are grey-green or glaucous in colour. It has white flowers that usually form groups of 7.[1][3][4] Distribution and habitatThe Tumbledown Red Gum is a tree that inhabits rocky slopes. It is particularly well suited to skeletal volcanic soils, usually on ridges, rises and escarpments.[5] It is similar to two other red gums, Blakely’s Red Gum (Eucalyptus blakelyi) and Dwyer’s Mallee Gum (Eucalyptus dwyeri).[3] UsesThe NSW Department of Primary Industries considers that it provides useful medium level cover in windbreaks; can be useful for recharge control plantings; and has potential for woodlot plantings. More commonly it is a valuable wildlife habitat, providing nectar and pollen for native birds and insects. The wood is fairly durable; used for fenceposts where suitable and firewood. It is a good quality honey tree.[3] References1. ^1 {{cite web|url=http://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Eucalyptus~dealbata|title=PlantNET - FloraOnline|work=Nsw.gov.au|accessdate=2015-06-25}} 2. ^{{cite web|url=http://avh.ala.org.au/occurrences/search?taxa=Eucalyptus+dealbata#tab_mapView|title=Search: SPECIES: Eucalyptus dealbata - Occurrence records - Australia's Virtual Herbarium|work=Ala.org.au|accessdate=2015-06-25}} 3. ^1 2 {{cite web|url=http://www.dpi.nsw.gov.au/agriculture/resources/private-forestry/paddock-plants/Eucalyptus-dealbata-Tumbledown-Red-Gum.pdf |format=PDF |title=Tumbledown Red Gum |publisher=Dpi.nsw.gov.au |accessdate=2015-06-25}} 4. ^{{cite web|url=http://www.australiaplants.com/Eucalyptus_dealbata.htm|title=Eucalyptus dealbata - Tumbledown Red Gum|work=Australiaplants.com|accessdate=2015-06-25}} 5. ^{{cite web|url=http://diversitynativeseeds.com.au/species-list-by-image/eucalyptus-dealbata-tumble-down-red-gum/|title=Eucalyptus dealbata. tumble-down red gum|work=Diversitynativeseeds.com.au|accessdate=2015-06-25}} Further reading{{Portal|Trees}}
