Buddleja saligna is a very hardy, evergreen, fast growing, drought resistant small tree or larger shrub for a small indigenous garden in Gauteng – especially if you are aiming for creating a living landscape with a high biodiversity. It grows up to 800 mm per year.
In larger gardens it is quick screen plant, hedge or windbreak. It is useful as a pioneer tree for a new forest garden. It also makes a very good clipped hedge. It is evergreen, frost hardy and drought resistant and the masses of sweetly-honey-scented white flowers make a lovely spring and summer show. It will grow in most soils but added compost will improve performance. It may need cutting back after flowering to keep tidy. The false olive does not have an aggressive root system.
According to PlantzAfrica Buddleja saligna is used for traditional medicinal purposes, the roots as a purgative and the leaves to treat coughs and colds. The wood is very fine grained and was used to make small pieces of furniture. The straight branches were used to make fence posts. The false olive was used to make assegai handles. It also makes good fuel wood as it burns with an intense heat. The large amounts of pollen and nectar it produces makes it popular with bee farmers.
