SelecTree: Tree Detail
AUSTRALIAN TEA TREE
Photo Locations: Alameda Plazas, Alice Keck Park Memorial Garden - Santa Barbara, CA, Huntington Botanical Gardens - San Marino, CA, Disneyland - Anaheim, CA and San Diego, CA
Australian Tea Tree is an attractive shrub or multi-trunked tree, becoming a graceful specimen when its lower branches are trimmed away to expose the picturesque trunks. The foliage is quite pleasing and used in bouquets. It is ideal for a temperate dry setting, where it usually attains less height, and it becomes quite durable after it becomes established. It may require regularly scheduled light top-trimming (but not necessarily shearing) of vigorous top shoots to maintain its height below 25'. Best near the coast.
Cal-IPC (California Invasive Plant Council) classifies the invasiveness of this plant as watch.
Native to Eastern Australia.
A Leptospermum laevigatum in Los Angeles is registered as a California Big Tree. It measures 15 feet high, with a trunk circumference of 84 inches and a crown spread of 18 feet.
