Oxalis bowiei Oxalidaceae John and Barbara Hopper, Kenwood John and Barbara Hopper, Kenwood This is a well-behaved South African species best grown as a pot plant. It is a summer grower with beautiful leathery “shamrock” leaves and clear pink flowers. It is best kept barely moist in winter and may go deciduous. The clumps can live for a long time.
