Annual Veldt Grass
(Weed)
Ehrharta longiflora

Annual Veldt grass, as the name suggests is an annual species, that can grow up to one metre tall, with very distinctive purple colourings on the base of the leaves and in the flower or seed heads. The flower, or seed heads, are in a slender inflorescence often with the spikelets drooping on one side of the flowering stem.

Originating from South Africa, Annual Veldt Grass now occurs in most disturbed areas and areas of native vegetation.
