Species:obassia

Family:Styracaceae

The fragrant snowbell is a flowering tree characterized by its large leaves, which can grow up to 8 inches long. Each spring, as the leaves develop, the tree showcases clusters of fragrant, white, bell-shaped flowers that hang gracefully in terminal racemes, also reaching lengths of 8 inches, creating a striking display. Following the blooming period, drupes form and can persist into late autumn.

Older trees may exhibit bark that peels away, revealing a vibrant inner layer that adds visual interest during the winter months.

In its early years, the tree has a pyramidal to oval shape, but as it matures, it becomes more open and rounded, with branches that ascend. To maintain its desired shape, winter pruning is recommended.

In terms of pests and diseases, frost can pose a threat to both the leaves and flower buds.
