NZ has approx. 200 species of ferns. From small 20mm filmy ferns to 10m high tree ferns. Ferns require lots of water so are typically found in moist forested areas. The leaves of ferns are called Fronds. Young fronds are coiled tightly into a spiral. The Maori call this “Koru”. The Koru is a popular motif in many NZ designs. Ferns have different growth forms from tufted, creeping, climbing, perching and tree ferns.
