Swamp Astelia - Astelia grandis

Astelia grandis is an evergreen perennial that forms dense clusters of stiff, arching, spear‑shaped leaves, reaching up to 2 metres tall.

Traditionally, it was harvested from the wild as a valuable source of both food and fibre.

Today, Astelia grandis is often grown as an ornamental plant for its striking foliage. It is dioecious, so both male and female plants are needed if seed production is desired.

Growing conditions:

  • Prefers sheltered, semi‑shaded sites
  • Hydrophyte: thrives in wet or moist terrain
