Plant in full sun to shade and irrigate occasionally to regularly - as with most Pittosporum this plant is relatively drought tolerant in coastal California gardens once established but looks best with an occasional deep watering. Hardy to at least 15 F. A very adaptable shrub that will tolerate seaside conditions, inland heat and alkaline soils.

Pittosporum tobira is native to Japan, the Ryukyu Islands and China. It was one of the first of the Pittosporum to be collected by the German naturalist Engelbert Kaemfer in the late 1600s and he illustrated and described it in 1712 using the Japanese name "tobera" but this was changed to tobira when Carl Peter Thunberg described it in 1784 as Euonymous tobira and then Pittosporum tobira when Carl Ludwig Willdenow reclassified it as a Pittosproum in 1797. The name for the genus comes from the Greek words 'pitta' meaning "pitch" and 'spora' meaning "seed" in reference to the sticky seeds of many members of the genus. The specific epithet comes from a translation of the Japanese common name. Often just called Tobira or Mock Orange (a name shared with many other plants) but also commonly called Japanese Cheesewood or Japanese Pittosporum.

Pittosporum tobira has been in cultivation in California since first being introduced in 1858 by Colonel J.L.L. Warren. Often called "Colonel Warren" or "Alphabet Warren", he was an early British immigrant who came to Sacramento in 1849 and operated a seed and agricultural implement business there. Warren also founded the California Farmer magazine in 1854 and later managed and funded the first California State Fair. A tree in Orange, California is registered as a Pittosporum tobira 'Variegata as well the very attractive Pittosporum 'Oakleaf', which maybe a selection of Pittosporum tobira or a hybrid. This species was awarded the prestigious Royal Horticulture Award of Garden Merit in 1993.
