Pittosporum: Greenhouse Plants
FF – frost free only/C – cool, minimum of 7°C (45°F)
Although most of these can be grown outside albeit in a sheltered place Pittosporum tobira from China and Japan is only half hardy and a good candidate for the greenhouse. Unlike the daintily leafed species used for flower arrangements this one has comparatively large oval leaves. It will remain a shrub of 1.2 m (4 ft) if planted in a pot but may become a little taller if planted in the border. It has cream coloured orange blossom-scented flowers during summer. The variegated form is particularly attractive. Cuttings preferably of semi ripe wood with a heel are best taken in late summer. Alternatively, seed is available which surprisingly enough germinates better if dipped into boiling water for a few seconds. A temperature of 13°C (55°F) is best for germination.
