Syringa – Melia azedarac
This large, fast growing tree, which can reach up to 23m high, is in full bloom at the moment. It has serrated, dark green, glossy leaves which turn yellow in autumn. Clusters of purple to lilac flowers, which are heavily scented, appear in spring. Numerous green berries turn yellow and wrinkled when ripe. The leaves, bark, flowers and ripe fruit are poisonous.
Syringa is one of the most widespread of all problem trees throughout South Africa and particularly in KZN. It produces an abundance of berries and the seeds, which germinate easily and are spread by birds, other animals, water and human activities where it establishes itself easily in all habitats, especially riverine areas, competing with and replacing indigenous vegetation, blocking waterways and reducing stream flow.
Flowering period: September to November. Berries: December to September
To eradicate this tree, cut off low down and paint the freshly cut stump to prevent regrowth with an appropriate herbicide, ensuring that instructions on the label are followed for your own safety. For large trees apply the herbicide using diesel as a carrier / penetrant, in a ring around the base of the tree trunk. For very large trees that are close to a building, wall or roadway, consider hiring an expert to cut the tree down.
