Description

  • A robust herbaceous plant forming large rosettes, or bold clumps of silvery-green, sword-shaped leaves.
  • Leaves: 30-60 cm long by 4-10 cm wide, stiff and of a leathery texture with the upper surface silver or silvery-green, the undersurface white.
  • Flowers: The stout flower stem is up to 50 cm long and the flower heads are 4-10 cm in diameter.

In addition to the typical form, two subspecies exist:

  • ssp. stricta: Has narrower and more rigid leaves with heavily rolled margins; their upper surfaces are also very silvery.
  • ssp. aurigens: The upper surfaces of the leaves are varying shades of gold.

Celmisia semicordataDistribution & Habitat

  • South Island, usually in subalpine to low-alpine regions. 600-1400 metres.
  • Common in snow-tussock grassland, herbfields and open subalpine scrub.
  • Typical form: Occurs throughout the higher rainfall regions from Nelson to South Canterbury and northern Fiordland. Sporadic in Nelson and northern Westland.
  • ssp. stricta: is restricted to the mountains of western Otago and adjacent Southland to the Takitimu Range.
  • ssp. aurigens: Occurs in Central and eastern Otago, with outlying populations in south-eastern Otago, and in Southland on the Garvie Mountains.

Notes

  • Identification: In all of its forms this is an outstanding plant which should be immediately recognised, even if not in flower.
