Creeping inch plant

Callisia repens

Creeping inch plant is an herbaceous species that has been widely cultivated as an ornamental plant in gardens. It has creeping stems that are much branched and produce roots at their joints. Leaves are densely clustered along the stems.


Crimson cestrum

Cestrum elegans

Crimson cestrum invades disturbed rainforest margins, moist and wet sclerophyll forests, urban bush land and creek banks. In these situations in takes over and displacesindigenous shrubs and smalltreesand restricts thehabitatof native wildlife. 


Crofton weed

Ageratina adenophora (Asteraceae)

Perennial or shrub up to 2m high with hairy stems. Dark green, non-aromatic leaves 30-60mm wide. White flowers in terminal clusters from August to December. This plant is poisonous. 


Dalmatian toadflax

Linaria dalmatica

Dalmatian toadflax is a grassland invader indigenous to the Mediterranean region. It looks like a large, yellow snapdragon and has fast-growing, strong, horizontal roots. It can withstand cold, although most of the upper stems die back in winter and new stems emerge in spring. It is a problem on farms and grasslands in the interior of South Africa.


Delta arrowhead

Sagittaria platyphylla

The delta arrowhead is an aquatic plant growing up to 150cm tall. It is green in colour, fast growing and can be placed in a variety of locations within an aquarium. The plant reproduces by means of stolons as well as seeds. Some leaves are totally submerged, others emergent (rising above the surface of the water). Submerged leaves have flattened petioles, but no true blades. Emergent leaves have ovate to elliptical blades.


Dense water weed

Egeria densa (Hydrocharitaceae)

A submerged aquatic plant with slender stems up to 3m long. Green, finely serrated leaves 15-30mm long in whorls of 4-5, sometimes 3-8. Yellow or cream flowers appear on long stalks about 20mm above the water surface. This aquatic plant invades still or slow-moving water in lakes and ponds.
