Leptospermum laevigatum

About

Gaudium laevigatum, commonly known as the coast tea tree, is a species of shrub or small tree that is endemic to south-eastern Australia, but has been widely introduced in other places where it is often considered to be a weed. It has thin, rough bark on the older stems, narrow egg-shaped leaves, relatively large white flowers and flat topped fruit that is shed shortly after reaching maturity.
