Origin of Scientific Name

Eucalyptus (Greek), meaning well and calyptos (Greek), meaning covered referring to the cap which covers the developing flowers.

preissiana after JA Ludwig Preiss (1811 - 1883), botanical collector.


This small tree occurs in the south-western provinces of Western Australia. Growing 2-3 metres in height and width, Eucalyptus preissiana is perfect for smaller gardens. With smooth bark and oval shaped, thick green leaves which taper to a point, this tree makes an interesting focal point for a garden.

When in flower, large vibrant yellow flowers form a prominent display along the branches, with blooms up to an impressive 30 mm or more in diameter. The Bell-fruited Mallee flowers in winter and spring with flowers followed by the most interesting large, bell-shaped gumnuts, giving Eucalyptus preissiana its common name: the Bell-fruited Mallee. In addition to their showy display, the flowers are highly bird attracting for nectar feeding birds.

Horticultural tips

  • Plant Eucalyptus preissiana in well drained soil: it grows well in sand, free-draining clay and gravel soils, in a full sun position.
  • This tree is difficult to grow in tropical and sub-tropical climates as it prefers temperate climates.
  • The Bell-fruited Mallee is best planted in the autumn and winter months in warm climates, but may struggle to survive winter conditions if planted while small in cooler areas.
  • Apply a slow release native fertiliser at the time of planting, and water well. Continue to water well at least twice a week during the first summer and into autumn, until the rain is regular. Once established, supplementary watering may not be required.
  • This tree responds well to hard pruning to near ground level if rejuvenation of the plant is required.
  • Can be susceptible to scale.
