Corymbia torelliana, known as cadaghi or cadaga, is a fast-growing tree from north Queensland that reaches 25 to 30 metres and is often grown as a street or garden shade tree. It is a weedy invader in coastal areas, so consider native alternatives.

About
Corymbia torelliana, commonly known as cadaghi or cadaga, is a species of tree that is endemic to north Queensland. It has smooth, greenish grey to white bark, rough at the base of older trees, egg-shaped, heart-shaped or lance-shaped adult leaves, flower buds in groups of three or seven, white flowers and urn-shaped or shortened spherical fruit.
How to grow it
Cadaghi is a fast growing tree that has been used as a street and garden tree further south than its natural range, including in inland towns such as Narrabri, Chinchilla and Cunnamulla. Its dense canopy of large leaves can provide shade in these places. A sooty fungus that often grows on the tree can discolour objects underneath it. Large branches can sometimes break off and there are serious environmental problems caused by this species in coastal and near-coastal areas. Less invasive alternatives include brush box (Lophostemon confertus), Moreton Bay ash (Corymbia tessellaris) and Queensland maple (Flindersia brayleyana ).
Where it grows
Corymbia torelliana grows in wet sclerophyll forest, on rainforest margins and as an emergent in rainforest. Its natural range is from Cooktown to Ingham and inland as far as the Windsor Tablelands. It has been used as a fast-growing garden and landscaping tree and has established itself beyond its natural distribution.
