Soapberry Tree Info
Soapberry (Sapindus) is a moderate sized ornamental tree that reaches heights of 30 to 40 feet. Soapberry tree produces small, greenish-white flowers from fall through spring. It’s the orange or yellow soapnuts that follow the blooms, however, which are responsible for the tree’s name.

- Hawaii soapberry is native to the Hawaiian Islands.

Types of soapberry trees that are not found in the United States include three-leaf soapberry and Chinese soapberry.
While this tough tree tolerates poor soil, drought, heat, wind and salt, it won’t tolerate frosty weather. Consider growing this tree if you live in the warm climates of USDA plant hardiness zone 10 and above.
Soak the seeds for at least 24 hours, then plant them in a small container at a depth of about an inch. Once seeds germinate, move the seedlings to a larger container. Allow them to mature before transplanting into a permanent outdoor location. Alternatively, plant the seeds directly in the garden, in rich, well-prepared soil.
Once established, it requires little care. However, young trees benefit from pruning to create a sturdy, well-shaped tree.
