Ferns are a very ancient family of plants, pre-dating flowering plants by 200 million years. In Celtic Paganism ferns are predominantly used for protection. An English tradition says that hanging dried fern leaves inside the house will protect the inhabitants. They can also be carried by travellers for this purpose The koru (Maori for loop), is spiral shape based on the shape of a new unfurling silver fern frond and symbolizing new life, growth, strength and peace. It is an integral symbol in Maori art, carving and tattoos. This example is a black tree fern native to New Zealand, but grown in Cornwall. Makes a great gift for any Kiwi to remind them of their beautiful homeland.
