Colobanthus kerguelensis is a small, moss-like cushion-forming perennial from the Caryophyllaceae family, native to cold subantarctic islands in the southern Indian Ocean. It is a wild species rarely grown in gardens, so care notes here are general guidance for cold, exposed conditions.
Colobanthus kerguelensis is a low-growing, moss-like flowering cushion plant in the family Caryophyllaceae, found on subantarctic islands in the southern Indian Ocean. The specific epithet refers to the type locality – the Kerguelen Islands.
As well as on Kerguelen, Colobanthus kerguelensis occurs on the Crozet, Prince Edward, and Heard Islands. It has been recorded from gravel substrates in the supralittoral or sea spray zone, in well-drained peaty and sandy soils with Azorella selago, and in feldmark, up to elevations of 30 m above sea level. It is a pioneer coloniser of recently deglaciated areas.
