Specific Information

Aloe thraskii is a tall, robust, single stemmed aloe with deeply U-shaped, olive-green arching leaves with red-toothed margins. Spines are sometimes also present in a line down the middle of the lower leaf surface. The long leaves curve strongly downwards, with the tips of the lower leaves touching the stem. The shaggy remains of old leaves cloak the trunk. Usually about 2 meters tall, Aloe thraskii  can reach up to 4 meters with a width of up to two meters. Mature specimens produce 3 or 4 branched flower stems with 15 to 25 erect cylindrical flower heads.

The Dune aloe grows fast in cultivation and is especially suited for coastal situations as it tolerates wind and salt air. It can be grown in inland gardens with mild winters and not overly damp summers.

Aloe thraskii is classed as Near Threatened in its natural habitat due to habitat loss from urban and coastal development and illegal collecting for the specialist succulent horticultural trade.

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
  • Accent or Focal Point A plant used to attract the attention because of its colour or form.
  • Attracts bees, butterflies or other insects This plant attracts insects which can be food for birds or other creatures in your garden.

  • Rock Garden An area constructed of larger rocks, arranged naturally, to emphasise the use of stones as a main element. Generally plants used do not need a lot of care.
  • Suitable for coastal gardens Plants adapted to dry, sandy soil, forceful wind, limited rainfall and intense sunlight.
  • Suitable for seaside gardens Plants that will survive the hostile environment of harsh salty winds, dry sandy soil, irregular rainfall and heat found in seaside gardens.
Distribution and Habitat

from Port St Johns in the Eastern Cape to aMatikulu (north of Durban) in KwaZulu-Natal, along the beach margin in dense coastal bush on dunes, no further than the top of the first sea-facing slope

Planting Suggestions

Plant in a full sun in very well drained soil. Ideal for planting on slopes, sandy or stony soil. Compost can be added to improve aeration and drainage. According to growers in the U.S.A. and Australia, Aloe thraskii can be grown in areas with light frost but needs protection.
