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

19 July 2025

Meet Lemon Myrtle Tree: Nature’s Lemon Zest Factory

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
