[Wikipedia] South Africa native: Kniphofia uvaria originates from the Cape Province of South Africa,[1] and has been introduced into many parts of the world, such as North America, Australia, New Zealand, Patagonia and Europe as a garden plant. It is hardy in zones 5 to 10. In parts of south-eastern Australia, such as the Central and Southern Tablelands of New South Wales and southern Victoria, it has escape cultivation and become naturalised.[1] It is now regarded as an environmental weed in these locations, spreading from former habitations into natural areas, where it can grow in thick clumps and threaten sensitive ecosystems. Elsewhere in southern Australia it is regarded as a potential environmental weed, and it may have also naturalised in parts of South Australia and California.[1] It is also seen in the Kumaon Himalayas of India, probably brought during the British period.
