Large-Leaf Yellow Teatree: A Hardy Australian Shrub for Hawaiian Gardens
If you’re looking for a low-maintenance flowering shrub that can handle Hawaii’s varied growing conditions, the large-leaf yellow teatree (Leptospermum morrisonii) might just be the plant you’ve been searching for. This Australian native has found a comfortable home in the Hawaiian islands, where it’s proven to be a reliable performer in gardens across the state.
Getting to Know the Large-Leaf Yellow Teatree
The large-leaf yellow teatree is a perennial woody shrub that typically grows as a multi-stemmed plant reaching heights of 13 to 16 feet, though it can sometimes grow taller or develop a single trunk depending on its environment. Despite its common name suggesting yellow flowers, this teatree actually produces charming small white or pink blooms that appear along its branches, creating a delightful display when in flower.
What makes this plant particularly appealing is its attractive narrow, leathery leaves and interesting bark that may peel in strips, adding textural interest to your landscape year-round.

Originally hailing from Australia’s coastal regions, the large-leaf yellow teatree has established itself throughout Hawaii, where it reproduces naturally without human intervention. It’s become quite at home in the islands’ diverse microclimates.
