Position
  • Canopy Shade Canopy shade is found below closely grown trees where some light filters through. Ideal for the protection of herbaceous plants.
  • Light or Dappled Shade Found below trees with sparse, open foliage. Ideal for the protection of herbaceous plants.
  • Partial Shade The area is in shade for part of the day and in full sun for part of the day.
  • Sun The area is in full sun for all or most of the day, all year round.
General Information
  • Attractive fruits, berries or seeds Brightly coloured fruits or berries increase and extend the visual impact of the plant and are especially attractive to birds and other small wildlife.
  • Drought Tolerance: High The plant is well adapted to arid conditions; it can survive long periods of drought and high temperatures without extra water.
  • Evergreen Plants that have leaves all year round.
  • Frost: Tender A plant that will not survive any frost or low winter temperatures.
  • Roots Non-invasive Safe to plant near pools, paving, walls or buildings.
  • Sand tolerant Plants adapted to survive in nutrient poor, very sandy soils.
  • Thorns / Spines / Prickles Thorn: A hard, woody, pointed branchlet. Spine: A modified leaf forming a hard, sharp-pointed outgrowth. Prickle: A small, sharp-pointed outgrowth growing from the bark of the plant.
  • Water Wise Plant species originating from low rainfall regions that require less water to survive and thrive than other plant species.
Specific Information

Dovyalis rotundifolia is a large shrub or small tree reaching to 7 meters, with dark glossy green, leathery leaves. It carries impressive spines of 8 - 12 cm long, making it ideal for inclusion in a barrier planting or for use as an impenetrable hedge. The flowers are inconspicuous but from January to March it bears striking clusters of small, orange-red, somewhat sour, edible fruits which are much loved by birds. It is relatively unknown as a garden plant and is endemic to the Sunshine Coast of the Eastern Cape.

Flowers
Description

small, inconspicuous, 10 - 20 white stamens

Season
  • Winter to Spring Plants will seldom bloom for the entire season as given in the list, but should flower during a period within these parameters.
Colour
  • greenish
Growth Rate
  • Moderate Specifying growth rate can be very misleading as there is considerable variation of growth rate depending on type and species of plant, available water, supplementary feeding, mulching and general care, as well as the plants suitability and adaptability to the garden environment.
Plant Uses
  • Attracts bees, butterflies or other insects This plant attracts insects which can be food for birds or other creatures in your garden.
  • Attracts Birds This plant will attract birds.
  • Barrier Plant A very thorny shrub, tree or scrambler that can be used to create an impenetrable barrier.
  • Border A strip of ground, at the edge of a driveway or path in which ornamental plants or shrubs are planted.
  • Boundary A plant useful for planting around the edges of the property to form a green or colourful backdrop, an impenetrable hedge, to hide walls or create privacy.
  • Filler Either a fast growing tree or shrub used temporarily to fill in an area while the permanent plants grow to a desired size, or a plant used to fill gaps in borders or beds.
  • Hedge Suitable trees or shrubs planted relatively close together so that the branches intertwine to create a barrier. This can be formal – the plants are regularly trimmed to produce a neat shape, or informal – the plants are left to themselves to create a natural hedgerow.
  • Suitable for coastal gardens Plants adapted to dry, sandy soil, forceful wind, limited rainfall and intense sunlight.
  • Wild Garden An indigenous garden planted for the benefit of wildlife and birds. Provides food, water, a variety of mini-biomes and no poisonous chemicals are used.
Distribution and Habitat

in the Eastern Cape, along the coastal belt from Humansdorp to East London, in coastal scrub and dune forest

Planting Suggestions

Plant in a sheltered position in well drained soil with compost and slow release fertiliser and water regularly to boost growth. Mulch well. Dovyalis rotundifolia responds well to pruning to shape and this may be best done while the plant is young.

The old method of digging a deep hole and filling it with soil and compost has resulted in many trees failing to thrive, dying, rotting at the base or worse still, falling over in later years due to poor root development.  Refer to the following sites for the best method of planting trees:

Medicinal Uses

The common sour-berry has pleasantly acid flavoured edible fruit.
