The Welwitschia has a low trunk and two leaves that divide and sprawl on the Namib gravel for the entire life of the plant, which can span many hundreds of years. If this weren’t enough, Welwitschia is a gymnosperm related to Mormon Tea (Ephedra) and produces seeds in cones, not from flowers. An individual Welwitschia plant produces either male or female cones, but never both. The age of the plants is difficult to assess, but they are very long-lived, living 1000 years or more. Some individuals may be more than 2000 yea...
