Leptospermum petersonii, commonly known as lemon-scented teatree,[2] is a species of shrub or small tree that is endemic to eastern Australia.

It has thin, fibrous or flaky bark, often strongly-scented elliptic to lance-shaped leaves, white flowers and fruit that are retained for several years.

It has thin, rough, fibrous or flaky bark on the stems, and glabrous branchlets that have a flange under the leaf bases.

[2][3][4] Leptospermum petersonii was first formally described in 1905 by Frederick Manson Bailey in the Queensland Agricultural Journal from a specimen collected by W.J.

The ability to be pruned regularly also makes it well-suited for hedges, windbreaks and harvesting for distilled essential oils.
