Ornamental ginger refers to ginger plants grown mostly for their attractive flowers and foliage. They may or may not be edible.
Either way, the flowers, and leaves are their highlighting feature. Originating in tropical regions, bright colorful flowers and fragrant flowers make ornamental ginger increasingly popular in non-tropical countries as well.
Edible ginger on the other hand is grown for its primary use of being edible either for culinary or medical purposes.
