There are 49 species of Dahlia and they come in almost every colour and hue except blue. They need at least 6 hours of sunlight each day to thrive; the more sun they get, the better they bloom. All dahlia flowers and tubers are edible. See https://www.thompsonmorgan.com/edibl...
They are beautiful and varied. If you check out the very end of this video, you'll see an example of a "dinnerplate dahlia" and how large they can be.
