The ginger plant is an herbaceous perennial that grows annual pseudostems about one meter tall, bearing narrow leaf blades.
Common ginger, also called culinary ginger, is one of the most popular edible types.
Not only are the rhizomes of common ginger edible, but so are its leaves and shoots—so feel free to chop them up finely and use them as a seasoning!
The leaves and shoots, meanwhile, have a less pungent flavor than the rhizome.
