Japanese Pittosporum
Pittosporum tobira
Japanese pittosporum is a dense, evergreen shrub native to warm-temperate and subtropical coastal forests of Japan, China, Taiwan, and Korea, prized for its leathery whorled foliage and intensely fragrant white flower clusters in spring. In suitable climates (USDA zones 8b-11) it is exceptionally tough - tolerating salt spray, drought, compacted soils, and heavy pruning - making it a staple of coastal landscapes, hedges, and mass plantings. The honest catch is twofold: it is frost-tender and will be killed or severely damaged below about 15°F, ruling it out for most of the continental US interior; and in mild Mediterranean-climate regions it escapes cultivation from bird-dispersed sticky seeds, where a Madrid study ranked it among the shrubs most associated with damage to native vegetation.
