Botanical name: Leptospermum scoparium
Leptospermum also known as a New Zealand Tee Tree are lovely trees, with flowers which resemble tiny wild roses and spiky little evergreen leaves. The bark looks old rapidly, although it may take a while to thicken the trunk.
During the summer you can place this tree outside to cut back on maintenance and provide ideal conditions. Bonsai trees should never be placed in full sun, and should be place in partly shady area. In the winter they need to be brought inside once the temperatures start dropping below 50 degrees. Like most other tropical bonsai it's very important to water daily.
