Leptospermum petersonii releases a powerful fresh lemon scent whenever the foliage is brushed or crushed, which makes it the obvious choice for a hedge along a path, a driveway or a boundary where people pass close by. Masses of small white flowers cover it through spring and summer.
The Lemon Scented Tea Tree grows to 3 to 5 metres tall and 2 to 3 metres wide at 30 to 60 centimetres per year, branching densely from ground level. It clips well into a formal hedge, works as an informal screen or windbreak, and can be lifted to a single trunk as a small feature tree.
This Australian native is frost hardy, surviving heavy and frequent frost without damage, and tolerates poor soils, coastal exposure and extended dry once established. It grows in full sun to part shade and needs only a trim after flowering.
Frequently Asked Questions
About Leptospermum petersonii
How tall does Leptospermum petersonii grow?
It grows to 3 to 5 metres tall and 2 to 3 metres wide, branching densely from ground level. It is easily held at 2 metres as a clipped hedge.
Why does it smell of lemon?
The foliage contains citral, the same aromatic compound found in lemon myrtle and lemongrass. Brushing or crushing the leaves releases a strong fresh lemon scent.
Can Leptospermum petersonii be used as a hedge?
Yes. It is one of the better native hedging plants, holding density under regular clipping. Plant 1 to 1.5 metres apart for a dense screen.
When does it flower?
Masses of small white flowers appear through spring and summer, attracting bees, native pollinators and small insect-feeding birds.
Is Leptospermum petersonii frost hardy?
Yes. It is frost hardy and survives heavy and frequent frost without damage, and also tolerates coastal exposure and extended dry.
Is the foliage useful for anything?
The leaves can be used to make a fragrant lemon-scented tea, and the essential oil is commercially distilled. The scent also deters some insects.
When should I prune it?
Trim after the main flowering flush finishes. Regular light trimming keeps the plant dense from the base and prevents it becoming leggy and open.
