Distribution and habitat

Distribution is mainly coastal, from central Namaqualand (Northern Cape) southwards to Cape Town and from there eastwards to the Knysna vicinity. However, it also occurs in more mountainous areas inland from the West Coast. It grows mainly in well drained, sandy soils on coastal flats, in areas dominated by restio tussocks, often growing in the restio clump. It also grows on stony mountain slopes up to 1000 m elevation.

Life cycle

  • A geophyte, with corms measuring 12-18 mm in diameter.
  • Flowers from June to mid-September.
  • Seeds are oblong, measuring 6-8 mm long by 5-7 mm wide, evenly winged.

Ecological interactions

Pollinators

  • Bees. Forage for nectar.
    • Anthophoridae. A range of species are attracted to Gladiolus carinatus flowers.
    • Apis mellifera (Honeybee)
