INDIGENOUS GARDENING:

CREATING ECOLOGICAL CORRIDORS

AND SUSTAINABLE LANDSCAPES

auteng, South Africa’s economic
heartland, is often associated
with urban sprawl, highways and
Ghigh-rise buildings. However,
amidst the development lies a unique and
diverse ecological landscape, home to
remnants of the Highveld grasslands, rivers
and wetlands. As urbanisation continues
to expand, the importance of indigenous
gardening has never been greater. By
cultivating native plants and creating
ecological corridors, we can enhance
biodiversity, reduce water consumption
and promote sustainable, low-maintenance
gardens.

The importance of indigenous gardening
Indigenous plants are naturally adapted
to Gauteng’s climate, soil conditions and
seasonal rainfall patterns. Unlike exotic
species, which often require additional
watering and fertilisation, indigenous plants
thrive with minimal intervention. This makes
them ideal for home gardens, parks and
public spaces, particularly in a water-scarce
country like South Africa.

Creating ecological corridors
One of the most powerful benefits of
indigenous gardening is the creation of
ecological corridors – connected green spaces
that allow wildlife to move freely between
habitats. Gauteng’s rapid urban expansion
has fragmented natural landscapes, making it
difficult for birds, insects and small mammals
to find food, shelter and breeding grounds.
By incorporating indigenous plants into
our gardens, we can create a network of
green spaces that supports local wildlife and
promotes ecological resilience.

Working with natural features
Understanding and using Gauteng’s natural
features can significantly enhance the
effectiveness of an indigenous garden.

The province’s landscape is characterised by:
• Highveld grasslands: These open,
grassy areas support a rich diversity
of wildflowers, birds and pollinators.
Planting species such as red hot pokers
(Kniphofia uvaria), wild iris (Dietes
