True cinnamon comes from the bark of an evergreen tree native to Sri Lanka and India which grows to a height of 8-20 metres. The leaves are petiolate, entire, mid green in colour with the underside being a paler green than the upper side, leathery ovate and up to 18cm in length. Young leaves are paler green with a reddish tinge, the leaves have 3-5 longitudinal veins. The 6-petaled flowers are approximately 3mm in diameter, pale yellowy-white in colour and form panicles of blooms which are 5-7cm in length. Flowers give way to fleshy fruits which are ovoid in shape, black in colour when ripe and 1.5-2 cm in length.
