Common name: Western coolibah or Smooth-barked coolibah
Origin of Scientific Name
Eucalyptus – derived from the Greek eu, well and calyptos, covered; in reference to the flower-bud which has an operculum or cap.
victrix – from the latin victrix meaning winner or victor.
Eucalyptus victrix is a small to medium evergreen tree with a spreading form growing to approximately 5-15 m high x 5-10 m wide. This species often grows irregularly, giving it character. The foliage is a dull light green to grey-green (glaucous). Peduncles terminal in groups of seven with conical to rounded operculum, flowers are relatively small, creamy white. It has a striking smooth white trunk.
Distributed throughout Western Australia and Central Australia, from Murchison River to Port Hedland and east into central Northern Territory. Usually found on flood plains and low lying areas of red clay or clay loam. Refer to the distribution map for this species via the Department of Parks and Wildlife's FloraBase online herbarium.
November to March
Best propagated from seed which germinates readily. Plant in late autumn in a full-sun aspect. Water well at the time of planting - it should not be necessary to give extra water unless there is a prolonged dry spell. Apply a slow-release 8-9 month fertiliser at the time of planting and annually if required. It is resistant to major pests.
This small ornamental tree is iconic due to the reference to its common name in the bush ballad Waltzing Matilda. The nectar attracts insects and birds and the sweet scent of the flowers will fill a garden. Plant this tree by itself or group several together to provide screening. To produce a distinctive desert garden use coolibah in association with other arid-loving species such as Eucalyptus pachyphylla, Eucalyptus kingsmillii, Eucalyptus youngiana, Triodia basedowii, Triodia bynoei, Atriplex nummularia, Senna artemisioides, Hakea rhombales and Ptilotus exaltatus.
