Data: Native to southeastern Australia and northwest Tasmania, this plant grows well near water, hence its name. It can grow into a tree, although is often pruned into a tall shrub for easier cultivation. As the shoots rise from the roots into thickets, the plant is often used as natural fencing. Rosalina is from the same botanical family as tea tree and is sometimes called lavender tea tree because it seems to have the properties of tea tree yet is calming, like lavender, and sweeter-smelling. Aboriginal people use the leaves and bark in their medicine.
