Leptospermum petersonii (or Leptospermum citratum), lemon-scented teatree is a tall shrub to small tree, growing to a maximum of 5 metres which is cultivated as an ornamental and for essential oils. It naturally occurs near sclerophyll forest or rainforest, on sandy or rocky escarpements, on the east coast of Australia. It has simple leaves, 20–40 mm long, with a distinctive lemony aroma. The flowers are white, followed by woody capsules.
Lemon-scented teatree is well known as a garden plant, popular for its scent and attractiveness. It is fast growing and can be kept to shrub height by pruning. The ability to be pruned regularly also makes it well-suited for hedges, windbreaks and harvesting for distilled essential oils.
Leptospermum liversidgei is also called "lemon-scented teatree" due to the presence of lemony essential oils.
