Riddonkulous

I wear a coat of orange bright, and hide a crunchy heart inside. I grow beneath the earth's dark floor, yet rabbits always ask for more. I have a crown of leafy green, the brightest snack you've ever seen. You pull me up and brush away the dirt, then crunch me down without a shirt. I help you see, or so they say, and make a tasty soup one day. Though I never run, I may be found in a garden hiding underground. What am I, the rabbit's favorite prize?
