The Gymea Lily (Doryanthes escelsa) grows naturally in open forest and woodland along the New South Wales Coast around Sydney and Newcastle. It makes a splendid specimen plant in a garden and can be bought from nurseries and garden shops. The plant keeps growing after the flower spike dies and I am told that the next flower will be even larger. In ideal conditions the spike can grow up to 6 meters tall.
The base of the plant - this also will grow larger.

Gymea lilies have pleasant memories for me. We lived in Newcastle when I was in my teens and my Father showed me this flower growing in the bush. He called it a 'Mountain Lily'. Although it is sometimes called a 'Giant Lily' I cannot find Dad's name for it in the references I consulted.
