After two or three years, I find the flowering performance of my Cape primroses starts to decline.
‘And I can hardly live without the Cape primrose, Streptocarpus ‘Black Panther’ - its velvet blooms are a treasure.’
The Cape primrose is also a cloud-forest plant, growing on the windward slopes of Table Mountain in Cape Town.
Otherwise, grow your Cape primrose the same way you would a gloxinia or African violet, with moderate light and household temperatures.
The understorey has been planted with many interesting South African forest dwelling trees, shrubs and groundcovers including Cape primroses and colourful spurflowers (Plectranthus).
