Gardening, no matter what you grow, will help you become healthy and
wise, as for wealthy well, that all depends upon how you define wealth.

Gardening will make you healthy through the act of gardening itself and
through eating the fruits of your labour; it will also make you wise as
you discover the wonders of growing things. Will it make you wealthy?
Well that is all up to you and what you believe wealth to be.
