Description
A bushy, evergreen tree with a medium-sized crown, growing 8-20 metres tall. Several parts of the tree are aromatic, including the leaves and bark, but it is most valued for the aromatic flower buds, which are usually harvested by hand. Leaves simple, bright green and glossy. The lower surface is covered in aromatic oil glands. Elliptical leaves with petioles (leaf stalks) grow up to 13cm long in opposite pairs along numerous short branches. Flowers developing in small clusters. Flower buds are initially pale with a glossy, fleshy appearance, turning green and then bright red as they mature. They consist of a long, narrow ovary, approximately 1.5-2.0 cm in length, with four small triangular sepals projecting outwards at one end. The sepals surround a small ball of four overlapping petals that protect the developing flower parts inside. It is in this form that the clove is harvested and dried for use as a spice. If the flower is allowed to mature, the petals fall off under pressure from numerous white-yellow stamens (male parts), which are then revealed. These showy stamens surround a single narrow stigma (female part). The fruit matures approximately nine months after flowering. The long red ovary of the flower gradually turns a reddish-purple and swells to the size of an olive, but is more oblong in shape with the sepals covering where the flower once was. The fruit contains one, or rarely two, seeds and is often referred to as the 'mother of cloves'. Cultivated clove trees are rarely allowed to reach fruiting stage (Kew)
