How to Grow Lemon Myrtle Tree in Australia: A Beginner’s Guide

19 July 2025

<strong>Meet Lemon Myrtle Tree: Nature’s Lemon Zest Factory</strong>

Lemon Myrtle Tree is an iconic Australian native shrub (3–8m tall) that thrives in subtropical rainforests along the coastal regions of NSW and Queensland.

Glossy green leaves release a crazy-intense lemon scent—like someone bottled sunshine and rainforest air. And after rain, the whole tree hums with citrus perfume. Seriously, I’ll stand there just breathing it in.

Scientific Name: Backhousia citriodora

Also Known As: Lemon-scented myrtle, lemon ironwood, sweet verbena tree

But the real showstopper? Summer. Creamy flower clusters burst open, and suddenly my garden’s buzzing. Bees dive-bombing blossoms, butterflies fluttering like confetti, even cheeky lorikeets stopping by for a sip. It’s alive
