Dicksonia squarrosa or Wheki, is a fast-growing and highly sought-after New Zealand native tree fern. Known for its elegant crown of deep green fronds, Wheki thrives in shaded environments, where it benefits from consistent moisture levels and protection from strong winds, particularly around the root zone. On the dry Canterbury Plains these tree ferns prefer south or east facing sites.

This versatile fern is a striking feature when planted in groups, creating a lush, layered effect, especially when underplanted with complementary ground ferns. Its vibrant, evergreen foliage ensures year-round visual appeal, while its hardy nature makes it well-suited for a variety of garden settings.
