  • Does not resprout after damage or fire.
  • Suitable for very extreme saline sites (ECe 800-1600 mS/m) (1)
  • Used as a street tree in Lord St, Bassendean (2)
  • Appears not to be a problem with sewerage lines (3).
  • Twenty-one compounds were identified in the oil of Eucalyptus spathulata with 1,8-cineole (72.5%) and α-pinene (12.7%) as main components. Although the 1,8-cineole is a main component of the essential oils of all Eucalyptus species tested, its relative content was higher in the oil of Eucalyptus spathulata and Eucalyptus torquata (4).
  • 1,8-cineole is also known as Eucalyptol (not to be confused with Eucalyptus oil).  Eucalyptol has a fresh camphor-like smell and a spicy, cooling taste. Because of its pleasant spicy aroma and taste, eucalyptol is used in flavourings, fragrances, and cosmetics. It is also an ingredient in many brands of mouthwash and cough suppressant. Eucalyptol has been demonstrated to be capable of reducing inflammation and pain. It has also been found to be able to kill leukaemic cells (5).
  • See our disclaimer. Anecdotal information suggests for example that throwing gum leaves into tea to add flavour is often acceptable but at certain times of the year the leaves are high in cyanide so can make the tea toxic!
