'It is out of the question the most wonderful plant ever brought to this country, and one of the ugliest.'This was the response of the Regius Keeper of the Royal Botanic Gardens, Kew, in 1863 when presented with a plant of Welwitschia mirabilis. Welwitschia mirabilis plants are unusual for their large, strap like leaves that grow continuously along the ground. During its entire life, each plant produces only two leaves, which often split into many segments as a result of the leaves being whipped by the wind. Carbon-14 datings of the largest plants have shown that some individuals are over 1500 years old.
