Corymbia (Eucalyptus) eximia
Family: Yellow Bloodwood
Yellow Bloodwood is the least commonly found of the temperate Corymbia species in Melbourne environs, but is an excellent tree for any non-frost-affected area. C. eximia originates in central New South Wales, from the Hunter River south to Nowra. It is typified by patchy, grey and brown bark, frequently on a crooked trunk.
The foliage of Yellow Bloodwood is broad-lanceolate, far broader than found on C. citriodora. It also differs from the more common bloodwoods, in that it is spring flowering, normally from August to October. C. eximia flowers for a relatively short time, but when it is in flower, the tree is a mass of creamy blooms.
C. eximia is noted for its ability to succeed on poor, gravelly or sandy soils, and its continuing health during droughts. With these functional capabilities, it is a tree that should be planted more commonly in Melbourne.
Yellow Bloodwood will suffer from frost damage, even when mature, and in a Melbourne winter, the normally bluish green leaves take on a pale yellowish tinge. When spring and warm weather return, this foliage discolouration fades very quickly.
Although there are few Yellow Bloodwoods in the Melbourne streetscape, cities to our north, including Albury, have used C. eximia successfully for many years. A smaller growing form, known as C. eximia ‘Nana’, grows to about 8m, and is a very suitable tree for height-restricted areas.
We recommend that municipalities order Yellow Bloodwood for trials in the next year, as we believe that this tree will survive on many difficult sites in the north and northwest of Melbourne.
Typical mature height: most often 12m in Melbourne
Useful in: streetscapes, avenues, parks
Sites for best growth: most soil types, full sun
