The tuart (Eucalyptus gomphocephala) is the largest tree on the Swan Coastal Plain, a coastal gum that can reach 40 m on Perth's limestone sands. It's one of the local eucalypts in our guide to the types of gum trees in Perth. Got one on your block? Here's what you need to know.
Key Takeaways
Tuarts grow naturally in a 400 km coastal band from Jurien Bay to the Sabina River near Busselton. The giveaway is rough, grey bark running up the trunk and into the main branches, unlike the smooth-barked gums nearby.
The name fits: gomphocephala means "club head", after those bud caps.
The Urban Bushland Council WA notes that tuarts grow to 40 metres, with a crown that spreads wide to match. That's why our native versus exotic trees guide flags tuart as a tree for large blocks only. Planted close to a house, it soon becomes a pruning and root problem.
Tuart woodlands were listed as Critically Endangered under national environment law, effective 4 July 2019. More than 111,600 hectares once covered the coastal plain, and much has been cleared for farms and suburbs. The listing applies to the woodland community, so whether one suburban tree is affected depends on its setting. Many councils also protect large trees on private land, so read our guide to Perth council tree removal rules before major work.
Tuarts are drought-hardy once established, so care is mostly about structure and safety. Our tree pruning team removes deadwood and reduces heavy, over-extended limbs to the Australian pruning standard, AS 4373. Lopping is the wrong call: it triggers weak regrowth. Keep trenching and parking off the root zone, too.
Unsure how healthy yours is? An arborist report gives you a documented assessment.
If your tuart is dropping limbs, crowding the house or showing dieback, we'll tell you honestly whether it can stay.
