Pittosporum tenuifolium ‘Tom Thumb’ is an evergreen shrub with a low, stout, bushy habit. Its foliage, borne on black stems, is wavy margined and thinly leathery, when young the leaves are a bright green and when mature it becomes flushed bronze-purple. It bears bell shaped, honey scented, black-red flowers that are followed by spherical woody fruits. These gray-black capsules then split open to reveal the reeds embedded in the sticky pulp.
The species Pittosporum tenuifolium is native to New Zealand where it is known by the Maori names Kohuhu or Kohukohu. The species grows wild in the coastal and lower mountain forests of both the North and South islands up to an altitude of 900m.
The etymological root of the binomial name Pittosporum is derived from the Greek pitte meaning ‘tar’ and sporos meaning ‘seed’, describing the sticky seed capsules. Tenuifolium is a Latin translation meaning ‘thinly leaved’. ‘Tom Thumb’ is in reverence to Charles Sherwood Stratton, a famous dwarf performer who went by the stage name General Tom Thumb.
