Hawaiian Kahili Ginger (Hedychium gardnerianum)

Unique ginger flower that only grows in high elevations.

If you've ever seen pictures of old Hawaiian cheifs, they had a pole next to them with yellow feathers attached to a cylindrical head. The poles were called kahilis and were a symbol of royalty. This ornamental plant looks like the kahilis, hence, it is called the Hawaiian Kahili Ginger. This plant has a nice fragrance and will grow at very high altitudes.
