Invasive Plants

African tulip tree

Spathodea campanulata

The African tulip tree is an evergreen species indigenous to western Africa. It has been introduced throughout the tropics and is threatening biodiversity in many parts of the Pacific islands. It favours moist habitats and will grow best in sheltered tropical areas. The tree invades both abandoned agricultural land and closed forest. This species loves rich soil, but puts up with just about any type of soil.

Aleppo pine

Pinus halepensis

A coniferous tree growing up to 15m high, conical in shape with a short trunk when young and rounded to oblong with a crooked trunk when older. Crown open with silvery-grey bark becoming darker. Grey-green to yellow-green leaf needles in bundles of two 4-8cm long. It invades grasslands and fynbos, particularly on dry soils

Algerian ash

Fraxinus angustifolia

The Algerian ash is a medium-sized, deciduous tree growing to 20–30m tall with a trunk up to 1.5m in diameter. It is not commonly planted anymore, however large numbers of adult trees can still be seen growing in suburban areas. The flowers are produced in inflorescences, which can be male, hermaphrodite or mixed male and hermaphrodite. Flowering occurs in early spring.

American bramble

Rubus cuneifolius

An erect to sprawling thorny shrub growing up to 2m high with deeply ridged stems. Green, finely serrated leaves sometimes densely grey-downy beneath. White flowers with petals that are much longer than the sepals and appear from September to January. The edible fruits are red turning black.

Ant tree

Triplaris americana

This tree grows 8-10m high with a straight, smooth, grey trunk with pyramidal crown. Leaves are bright green and smooth, or brownish-velvety beneath along the midrib and veins. Small male and female flowers on separate trees from April to May in large clusters, along densely greyish-yellow, light brown hairy axes. Female flowers red. Shiny brown fruits. Poisonous leaves.
