Leptospermum laevigatum is an evergreen shrub or small tree with an attractive twisting and spreading trunk that works well in informal gardens. The plants reach 20 to 30 feet in height as well as in spread when planted outdoors. Outdoor planting is possible in U.S. Department of Agriculture plant hardiness zones 9 through 11, and container planting is possible in colder climates to allow for wintering over indoors. Australian tea trees are easy to grow and generally do not require fertilizing, unless grown in soil that is known to be nutrient deficient or in pots where they can consume the limited nutrients available in their potting soil before requiring repotting.
