olive leaf

Olea europaea


Olive leaf comes from one of the oldest known cultivated trees in the world. The olive tree is indigenous to the Mediterranean region, as well as tropical regions of Asia and Africa. To the Ancient Greeks, its leafy branches symbolised abundance and peace, and were used as holy offerings. While its fruit is the best-known part of the olive tree, especially for the delicious role of its oil in the ‘heart-healthy’ Mediterranean diet, it’s the olive leaves that have drawn the attention of healing practitioners throughout the centuries.

Domestic & culinary uses

Although the leaves are not used in cuisine, olives, and especially their oil, feature widely as part of a healthy eating regime. In fact, a glug of olive oil enhances the flavour of most dishes.


Olea europaea is a hardy, drought-resistant tree that thrives along the Mediterranean. It grows easily in South Africa. The small subspecies Olea europaea subsp. africana is equally hardy and is an excellent small tree in gardens. Its white flowers, borne between October and February, are sweetly scented and are followed by small, purple-back olive fruits.
The easiest way to plant an olive tree is to buy a good-sized specimen in a container. Plant in a well-prepared hole to which bone meal, superphosphate and compost have been added, and mulch thickly. Water when dry.
