Eucalyptus lansdowneana, Crimson Mallee, is a small tree that will reach a height of six metres. In the wild plants usually have multiple stems (mallee growth habit) but in cultivation plants usually restrict themselves to a single trunk.
Bark is persistent on the lower stems, otherwise smooth and shed in long strips.
Leaves are 15 centimetres long, two centimetres wide, leathery, lanceolate and yellowish-green to grey-green.
Buds, flowers and fruits are held in groups of seven. Flowers are an eye-catching dark pink to crimson-red. They make an appearance from autumn to spring.
Fruits are cylindrical to somewhat urn-shaped and slightly ribbed or angled.
Crimson Mallee is endemic to South Australia where it is found in the Gawler Range, north-west of Adelaide.
Eucalyptus lansdowneana is classified as rare because of its limited distribution but is widely cultivated in South Australia.
E. lansdowneana is a beautiful small tree that is very hardy and could be grown as a “stand alone” specimen plant or incorporated in a native shrubbery. The Crimson Mallee is small enough to be cultivated in suburban gardens.
It has very attractive red to pink to cream flowers. It reportedly grows best in full sun on alkaline soils but can be tried on acid soils. Can be pruned to create a mallee habit. Great for birds and bees.
Propagate from seed.
This species can regenerate from the lignotuber after fire as well as any seedbank.
Eucalyptus – from Greek, eu, “well” or “true” and calyptus, referring to the calyptra (καλύπτρo) or operculum, which is a bud cap or covering which covers the developing flowers. The calyptra is a fusion of petals and/or sepals and is shed when the flower opens, leaving a flower with many stamens (staminate) surrounding one female part (carpel).
lansdowneana – The species name commemorates Thomas Lansdowne Browne who owned Pandura Station and collected the type specimen.The type specimen was collected on Pandura Station, South Australia and named in 1889.
This species is not considered to be at risk of extinction in the wild but is considered rare and has a small geographic distribution.
