Heart-leaf Mallee, Eucalyptus websteriana.View image slideshow

Origin of Scientific Name

Eu - Greek word for well
Kaluptos - Greek word for covered

The combination of these words refers to the bud cap which covers the unopened flower of the Eucalypt.


Eucalyptus websteriana is one of a suite of small ornamental trees endemic to Western Australia. Growing up to 3 metres high, with minni-ritchi bark and heart-shaped leaves, this small tree is compact and provides only lightly dappled shade, meaning any undergrowth plants will not suffer as Eucalyptus websteriana grows.

This variety of Mallee can be easily confused with Eucalyptus orbifolia, however is easily identified by its smaller, greener leaves which are longer and wider. You will also notice that Eucalyptus websteriana doesn’t have a white, waxy coating on its fruit.

Eucalyptus websteriana flowers from September to November, with a subtle show of feathery yellow flowers, and ornamental, globular buds and fruit. Similar ornamental Eucalypts closely related to this species also having minniritchi bark include E. ewartiana, E. orbifolia and E. crucis.

Horticultural tips

  • Eucalyptus websteriana can survive in a low water use garden, provided it is watered regularly until established. Avoid overwatering and / or fertilising.
  • This tree grows well in heavy soils, as long as it is well drained.
  • The growth habit of Eucalyptus websteriana encourages shaping and feature pruning.
  • For those with a smaller garden, Eucalyptus websteriana can be grown in a large tub using native potting mix.
