Another flower that is flourishing in the neglected historical cemetery in Grahamstown is the Vinca (Catharanthus roseus).
Apparently originating from Madagascar, these tough plants seem to flourish sans care in our hot and dry conditions. Thus it is no surprise that it is known as Kanniedood (cannot die) in Afrikaans. Its toughness and ability to seed itself and flourish anywhere has also earned it the moniker of ‘graveyard flower’ in some parts of the country. Another common name is Rosy periwinkle.
These flowers were most likely introduced as a useful ornamental plant – who would turn down flowers that bloom in the drought – but, like so many ‘imports’, has escaped beyond garden borders to become particularly invasive in KwaZulu-Natal, Mpumalanga and Limpopo. So widespread is this flower that it has become naturalised in practically all tropical countries.
I clearly recall these flowers growing ‘wild’ in our garden in Mpumalanga when I was a child. It was one of the few flowers my mother did not mind me picking to decorate the various fairy gardens I created in between the roots of some of the trees.
The flowers are pollinated by butterflies and moths. Seeds tend to be dispersed by ants, wind and water.
