Dombeya rotundifolia (Wild pear)

Each month, our readers look forward to our featured tree review. We conduct in-depth research into each species, to obtain as much information as we possibly can in order to offer you a truly valuable, expansive information resource. All the trees we feature are indigenous species which are suitable for use within commercial and residential landscaping projects and are easily grown throughout most of Southern Africa, but specifically the Western Cape.

The charming Dombeya rotundifolia is a common sight in bushveld areas where it heralds the onset of spring when it literally covers itself in a profusion of white or pinkish scented flowers before the leaves appear. This highly ornamental small tree with it’s neat rounded, spreading crown and almost delicate appearance resembles a true pear tree when it flowers, giving rise to the common name Wild pear. The lovely flowers contrast sharply with the dark bole and branches creating a spectacular show. The rounded dark green leaves appear after flowering, in summer, turning a beautiful lemon yellow before falling in autumn. This fast growing small tree is amazingly tough and will withstand drought, frost and windy conditions.
