Crataegus monogyna in Ennerdale, England.
Welwitschia mirabilis is a species I never cease to be excited about. This species is endemic to the Namib desert, in Namibia and Angola. It is a monotypic species. Which appears to have remained unchanged for tens, maybe even hundreds, of millions of years. Pretty incredible, but it gets better!
W. mirabilis produces two cotyledons upon germination. These grow into two leaves. These leaves remain as the plants only leaves, for its entire life. Each leaf can reach four metres in length. Considering W. mirabilis can live for over a thousand years, its amazing.
Eli (head gardener) ordered some seeds a while ago and they came yesterday. They were soaked for 24 hours then sown in deep tubes. W. mirabilis resents root disturbance, so it must be repotted before it reaches the base of the tube.
