Backhousia citriodora 'Lemon Myrtle'

Lemon Myrtle (Backhousia citriodora) is an evergreen tree native to the subtropical rainforests of northern NSW and southern Queensland.

This species typically grows 3–20 metres tall with a canopy spread of 1–5 metres. Its defining feature is glossy, aromatic foliage rich in citral, the compound that produces its characteristic lemon scent.

Delicate white flowers appear in terminal clusters during warmer months.

The plant thrives in full sun with well-drained soil and benefits from warm, humid conditions.

Regular watering and balanced feeding during active growth periods encourage abundant new foliage suitable for harvesting.

While moderately frost-tolerant, extended cold exposure can damage leaves. Apical pruning maintains a compact form and promotes fresh juvenile growth.

Prized for its high essential-oil content and distinctive sensory qualities, Lemon Myrtle serves dual purposes as both a culinary herb and an attractive ornamental specimen.
