Think I will try growing some this year.

The ginger used in cooking and shown in the Web page you cite is
Zingiber officinale. It's hardy to about 22F. It requires heat and
high humidity in the summer.

Shell ginger (an ornamental) is part of the genus Alpinea. They are
hardy to about 15F. They require shade and protection from winds.

Ginger lilies (another ornamental) are in the genus Hedychium. They are
hardy to about 20F and also require high humidity.
