Wild-Oat

Wild oat grass appears in midwinter in some areas, but takes a few weeks to grow to its maximum height of 1-4 feet before it releases pollen. It produces long waving fronds from August.

Bunny-Tail

Bunny tail grass

‘Bunny tail grass’ appears in September-October. It is found in sandy soil but is rarely seen in the heavier soil of the land close to the mountains in the Cape.

Thatch-Grass

Thatching grass is very tall and widespread in South Africa, but is mostly found in the grassland areas of Gauteng and the Eastern Cape, and releases pollen from September to June.

Bermuda-Grass

Bermuda grass must be tested separately when patients undergo grass sensitivity tests because it does not cross-react as most other grasses do. It grows most happily in sandy soil and releases most pollen in late summer but it may be seen throughout the year.

Buffalo-Grass

Buffalo grass

This indigenous African grass is known as buffalo grass and is a coastal grass. It may be seen in the Cape, especially along the east coast and on the Otter Trail between Knysna and Nature’s Valley.
