New Zealand native fern from my garden.

New growth.

• The leaves of ferns are called fronds and when they are young they are tightly coiled into a tight spiral. This shape, called a ‘koru’ in Maori, is a popular motif in many New Zealand designs.
• One notable New Zealand fern is bracken (rarahu), which grows in open, disturbed areas and was a staple of the early Maori diet in places too cold for the kümara to grow. The roots were gathered in spring or early summer and left to dry before they were cooked and eaten.
