Eucalyptus_gregsoniana.jpg (48392 bytes)Eucalyptus gregsoniana: is a member of the Myrtaceae family whose accepted common name is Wolgan Snow Gum. Wolgan is a locality in the Blue Mountains, west of Sydney.

In the wild the Wolgan Snow Gum usually develops a mallee type growth habit with multiple trunks. Cultivated specimens usually have a single trunk. In both cases plants will reach a height of about six metres. The bark is smooth, white or grey and shed in ribbons.

Leaves are up to 10 centimetres long, 2.5 centimetres wide, lanceolate, leathery and grey-green on both surfaces. The minor veins, on the leaves, are almost parallel with the prominent mid vein. This is a distinctive feature. Usually the minor veins, on eucalypt leaves, are at an acute angle to the mid vein. The venation pattern is illustrated in the photograph.

Flowers are carried in clusters of from 7 to 11; each bloom is 1 centimetre across, white and appears in late spring. Blooms are followed by small gum nuts that are 8 millimetres long by the same width and pear-shaped or globose.

Eucalyptus gregsoniana, because of its size, would make an ideal specimen plant for suburban gardens.

Eucalyptus gregsoniana was previously known as Eucalyptus pauciflora var. nana.

The Wolgan Snow Gum has a sporadic and scattered occurrence in New South Wales. Distribution extends from the Blue Mountains, west of Sydney, to the Southern Highlands of NSW. The species is considered rare because of small populations but is adequately protected in national parks. Also Eucalyptus gregsoniana is becoming popular in cultivation. So the species meets the two criteria for survival: conservation and cultivation. Populations are protected in reserves and gardeners are growing the species.

The Wolgan Gum is a very hardy, free flowering species. We first saw a specimen in Kew Gardens, London where it was growing outside and in full flower.

Propagate from seed.
