It is one of the most widely cultivated of Australia's native trees. It can be found in parks and gardens in many parts of Australia and is well established overseas (eg. Algeria, Brazil, France, India, Spain and Portugal). In California it is so well known that many regard it as a native Californian species. Heartwood Color Yellow Red Brown Orange Pink Yellow to golden-yellow to orange Pale brown Pale red to pink Greenish to greyish Dark cream Brown Sapwood Color Paler than heartwood White to yellow Sapwood is considered narrow Pale cream Grayish white Grain Interlocked Wavy Straight Even Figure Spiral Closed Crossed Rippled (figure) Growth rings (figure) Interlocked Wavy Straight With distinct light and dark bands Spiral Spiral grain occasionally Rippled figure Bees wing' curl figure is fairly common. Texture Fine Medium coarse Medium Fairly open Luster Dull Slightly lustrous Lustrous Natural Growth Defects Brittleheart is often frequent and extensive Gum/resin exudation Natural Durability Durable Susceptible to insect attack Resistant to powder post beetles Non-resistant to termites Moderately durable Moderately durable Susceptible to attack from termites (Isoptera) Susceptible to attack from powder post (Lyctid & Bostrychid) beetles Resistant to attack from marine borers Non durable Durable Susceptible to marine borer attack Non durable Moderately durable Durable Very durable Very durable Sapwood susceptible to attack by powder post beetles Resistant to attack from termites (Isoptera) Resistant to attack from powder post (Lyctid & Bostrychid) beetles Perishable Perishable Moderately resistant to decay Durable Sapwood is liable to be attacked by powder-post beetles and termites.
