This small evergreen tree is water wise and will thrive in the sun or semi-shade. Little white flowers open in summer and they are followed by little yellow fruit that look like miniature lemons and they attract insect and fruit eating birds like bulbuls, starlings, barbets, pigeons, guineafowl and francolins. The tree is also used for nesting sites and the leaves are browsed. It can be utilized for informal hedging/screening or thorny security barriers. It is an ideal tree for small gardens and looks great near a pond. As it does not have aggressive roots it can be planted in a container, near a building or paving.If the leaves start to drop, this is an indication that it is water deprived. The name comes from the Greek opsis=resemblance as the genus resembles Cassine.
