Pittosporum tobira
Easy · Beginner friendlyAbout Japanese Cheesewood
Pittosporum tobira, commonly called Japanese pittosporum or Japanese mock orange, is a dense evergreen shrub native to Japan, China, and Korea. It typically grows two to four meters tall with a naturally rounded form and thick, leathery dark-green leaves arranged in whorls at the branch tips. In late spring to early summer, it produces clusters of small creamy-white flowers with a sweet fragrance reminiscent of orange blossoms, which gradually age to pale yellow. The flowers give way to green seed capsules that split open to reveal sticky orange-red seeds — the genus name literally means 'pitch seed'. Pittosporum tobira is one of the most widely planted ornamental shrubs in warm temperate and subtropical regions worldwide. It excels as a hedge, foundation plant, or specimen shrub, and its salt tolerance makes it invaluable in coastal landscapes. The popular cultivar 'Variegata' features gray-green leaves edged in creamy white. The plant adapts well to pruning and shaping, and once established, it is remarkably drought-tolerant. It is a common element in both formal Western landscapes and naturalistic Asian-style garden designs.

History
Pittosporum tobira is native to coastal Japan, southern Korea, and coastal southeastern China, including Taiwan. Its Japanese name tobira means door, a reference to the old custom of placing branches at doorways during New Year celebrations to invite good fortune. The plant forms dense evergreen shrubs with glossy leaves clustered at branch tips, and in late spring it releases cream-white flowers with a powerful orange-blossom fragrance.
Introduced to European horticulture in 1804 through Kew, it became a workhorse of Mediterranean-climate landscaping because it tolerates salt spray, heat, drought, pollution, poor soils, and hard pruning. It has been planted by the millions as hedging, foundation planting, freeway landscape, and coastal windbreak in California, Florida, southern Europe, Australia, and New Zealand. Compact 'Wheeler's Dwarf' and variegated forms keep it common in modern gardens.
