Pelargoniums are well-known garden and windowsill plants throughout the world, but many people don’t know that the modern garden hybrids are based on a handful of wild South African species. At Kirstenbosch you can see the astonishing variety of wild Pelargoniums, at their best in spring summer (Oct-Nov.). Pictured: Pelargonium peltatum, the parent of modern Ivy-leaved Pelargoniums.
