Are You Familiar with the Smooth-Barked Apple Gum Tree?

Dive into the exciting world of the Smooth-barked Apple Gum tree, which goes by the botanical name, Angophora costata. A member of the Myrtaceae family, this tree can be found in the lush landscapes of north-eastern Australia. With an impressive mature height of up to 25m, this broad-domed tree presents dense foliage and striking, twisted limbs.

How to Decide the Perfect Spot for Your Apple Gum Tree?

These trees have a penchant for compacted soils and can withstand salty spray, making them quite resilient. However, they don’t fare well in waterlogged soil. If you’re looking to add an eye-catching feature to your garden, consider planting this tree, which is renowned for its twisting limbs and does not emanate the typical Eucalyptus scent!

What Sets the Angophora Genus Apart?

Although Angophoras share a close relationship with Eucalypts and Corymbias, they stand out with their unique characteristics. A genus of nine species within the Myrtaceae family, Angophoras have their leaves always positioned opposite each other on a branch, unlike their cousins. And if you’re thinking about taking a sniff, you’ll be surprised! When crushed, the foliage of these trees doesn’t exhibit the Eucalyptus-menthol scent that is a trademark of many gum trees.

What is the Growth Pattern and Appearance of the Smooth-Barked Apple Gum Tree?

The Smooth-barked Apple Gum, also called the Sydney Red Gum, can grow to a staggering 25m. Adorned with smooth bark, these trees have pale pink, orange, or grey limbs that twist and turn, giving a gnarled and crooked appearance, especially in older specimens. Come December, January, and February, their thick clusters of white flowers bloom, attracting a myriad of insects and nectar lovers. As the bark sheds during summer, the pale colours transform into a vibrant salmon-red hue, giving the tree another common name – the Rusty Gum.

What are the Tolerance Levels of the Angophora costata?

The Angophora costata displays a remarkable level of adaptability, taking on variable shapes – sometimes tall and slender, but more often evolving into a rounded, arched-shaped tree. Beware, though, as older trees may drop limbs. These trees can tolerate a variety of soil types and, once established, prove to be incredibly hardy.

Interesting Facts:

  • The smooth-barked apple gum tree is an important source of food for the koala bear.
  • In December, the apple gum tree displays a magnificent show of white, perfumed flowers.
