  • It grows best in full sun or semi-shade.
  • It tolerates a wide range of climatic conditions and soil types and performs best on well-drained sites.
  • It is moderate to fast growing and makes a lovely specimen tree.
  • It is suitable for hedge or screen use.
  • The bark can be used to grow epiphytic orchids. Epiphytic plants use other plants for support but are not parasitic.
  • In Boroondara, the Black she-oak can be found in Yarra Bend Park.

  • River red gums once spread across most of Boroondara. Now, they are found along the Yarra River and local creeks and in a few isolated sites like Cato Park and Belmont Park.
  • It is an important food and habitat resource with older trees providing vital hollows for nesting.
  • It historically provided the Wurundjeri people with bark for canoes and shields and gum to treat burns.
  • Its water-resistant properties have led to its use in constructing wharves and railway sleepers.

  • It prefers full sun.
  • It is an attractive tree and is suited to large gardens and parklands.
  • It requires a well-drained soil and is drought tolerant.
  • It can be used as an ornamental or amenity plant.
  • In Boroondara, Yellow box is scattered across reserves often as a single specimen tree. It can be seen in South Surrey Park, Cato Park, Kellet Reserve, Beckett Park, Nettleton Park and Willsmere estate.
  • It provides food for caterpillars and nectar for butterflies. It also provides habitat and food for birds.
