Native to China and Tibet, it is a broadleaf evergreen shrub that grows to a maximum of 8-10 feet tall. It has long been grown in gardens ornamentally, especially as a hedge or screen, in temperate gardens for its densely packed green foliage and the fragrant white to yellow flowers it produces in spring. As a landscaping plant, it is known for being more cold hardy than Pittosporum tobira and can be grown in hardiness zones 7-9 on the USDA scale.
