Kirstenbosch National Botanical Gardens (maintained by the South African National Biodiversity Institute in Cape Town) is one of the most important -- and most beautiful -- botanical gardens in the world. Nearly half of all plant species found in the southern half of Africa exist on one tiny sliver of land surrounding Cape Town. The Cape Floral Kingdom is home to an astonishing 6,200 species of plants found nowhere else on earth, and many of them are found in Kirstenbosch. Some are found only in Kirstenbosch, having gone extinct in the wild.
I wish I could have photographed every plant in the Gardens, but that would have been impossible, even if I had had a year in Cape Town (now there's a dream project!). My more realistic goal was to capture something of the magical beauty of this place, so that people outside of South Africa have a chance to experience it, if only in pictures.
