FLORAL COMPASS
gardens editor Heidi Bertish discovers an indigenous garden and thriving ecosystem planted as an ode to our local plant heritage
A local garden pays homage to the incredible biodiversity of the Cape Floristic Region
located on the south-western tip of south africa, the cape Floristic region is one of the most special places in the world for plants. While it represents only the tiniest sliver of the african continent – less than 0.5 per cent, to be exact – it has been declared a unesco World heritage site and recognised as one of the greatest centres of terrestrial biodiversity in the world. Thriving in an area equivalent to a single scale on a crocodile’s tail, the region is home to an astounding 20 per cent of the floral species on the entire continent. With a vision deeply embedded in south african plant heritage, this family garden, in the heart of the cape Floristic region, grew from an intimate connection to the endemic plant life of the area. ‘We had been looking for property in stellenbosch for a few years. While my husband examined the house, I saw the huge rock at the end of the garden and was sold instantly. That large granite boulder holds ancient energy,’ says the owner.
dds Projects was appointed to interpret the family’s dream of an endemic, indigenous garden. They wanted one that required very little watering and was able to establish its own ecosystem. Budget constraints necessitated imaginative thinking. hardscaping, irrigation and trees were identified as priorities which then left funds for only very young plants.
The family required a lawn, but not a traditional central lawn. dds Projects envisaged graphic, lawned conduits through a mix of low renosterveld plantings. ‘I love the geometric pattern of green paths, which lead to the woodchip path around the rock – meditative meandering often happens here. The paths are cleverly raised above the planted areas to direct rainwater coming off the rock to percolate into the soil.’
The new planting remained true to the swartland shale renosterveld vegetation that historically covered the area. Much of the fertile, clay-rich soils of old had been denuded to make way for new agriculture in the area and the planting of orchards, vineyards and cereal crops, forcing the renosterveld into isolated pockets, ultimately creating what is now a highly endangered vegetation type.
In an attempt to revitalise soil health, generous quantities of compost and bioorganic fertilisers were applied. ‘By using endemic plants adapted to this soil type and climate, we have created a garden that requires almost no supplementary watering, with a functioning ecosystem where pests are contained by local predators and the seasonal effects of the flora on the mountains and surrounding countryside are mirrored,’ says the homeowner.
apart from the usual suspects, the garden attracts drongos, Flycatchers, hoopoes, cape robin-chats, Fiscal shrikes, cape sparrows, cape spurfowl and sunbirds, which all breed in the garden. It also receives regular visits from Pied Kingfishers, Jackal Buzzards, cape Widowbirds and more.
as more gardens are planted with local plants, a widespread, self-sustaining ecosystem is created which uses less water and reduces reliance on pesticide and fertilisers. In the face of future water scarcity and ongoing habitat loss, it is a small but important contributor to the biodiversity and ecological health of our plant heritage.
