CARA Category 3

The Jacaranda is a deciduous or semi-deciduous tree up to 22m high with a rounded, spreading crown. It has dark green, hairy, finely divided and fern-like leaves which turn yellow in late autumn or winter. The flowers are attractive and are typically mauve-blue to lilac (rarely white) and tubular, produced in pyramidal sprays at the end of branches. They appear between September and November. Seeds are found in oval, flattish, woody green capsules about 60mm long, which turn brown and split open after about one year. This tree belongs to the Bignoniaceae family and originates from South America. Only Jacaranda trees outside the urban edge, primarily in the outer west areas, are being targeted where they are found to be spreading along drainage lines.

Why is it a problem?
It competes with, and has the potential to replace, indigenous species. Dense stands along watercourses are likely to reduce stream flow.
Control method
The Jacaranda is typically controlled my means of mechanical removal. There is an herbicide registered for it, but no biological control agents have been introduced.
Where is it a problem?
It is common throughout Mpumalanga, Limpopo, Gauteng and KwaZulu-Natal.
