Also called Narrow Leaf Black Peppermint, Narrow Leaf Peppermint, Small Leaf Peppermint, Willow Peppermint, Willow Leaf Peppermint, Narrow Leaved Black Peppermint
Eucalyptus nicholii is a small to medium tree native to the Northern Tablelands of New South Wales, widely planted in southeastern Australia for its fine, dense foliage. It is best kept in a sunny spot with moderate water, as well-watered trees can grow tall and shed large branches.

About
Eucalyptus nicholii, commonly known as the narrow-leaved black peppermint or willow peppermint, is a species of small to medium-sized tree that is endemic to New South Wales. It has thick, rough, fibrous bark on the trunk and branches, small, narrow adult leaves, flower buds arranged in groups of seven, white flowers and small, hemispherical, bell-shaped or conical fruit.
How to grow it
This tree is very widely planted as an ornamental in southeastern Australia, the fine, dense foliage being particularly attractive. It was often recommended as small enough to be suitable for planting on suburban blocks. However, when well-watered it sometimes grows inconveniently tall, and may shed large branches. Hence it sometimes appears on lists of problematic trees for suburban gardens.
Where it grows
The narrow-leaved black peppermint grows in shallow, relatively infertile soils overlying shale and slate bedrock usually as part of grassy or sclerophyll woodlands, in association with Eucalyptus andrewsii and Eucalyptus caliginosa. Its distribution is limited to the Northern Tablelands, New South Wales, particularly in the Walcha to Tenterfield, area and to the east. The species is sparsely distributed, but most commonly occurs in the central areas of its range.
