A rabbit's diet is very important. Rabbits can get bellyaches very easily, and you should never ever switch their diet quickly. Wean them off, little by little every day. A few bites won't hurt, like a nibble of parsley or something like that.
Rabbits need hay. NO alfalfa hay like horses eat. It must be grass hay, like orchard grass, timothy, brome, bluegrass, meadow grass, etc. Alfalfa is good for babies, pregnant and nursing rabbits, and some sick/underweight rabbits (at a vet's direction); but it's too high in calcium and protein for most normal adult rabbits.
Rabbits can eat certain vegetables and fruits - see below for examples. Dark leafy greens are good every day, but most fruits and vegetables are only good as a treat and should be strictly limited. The House Rabbit Society recommends no more than 2 tablespoons of treat foods per day for a normal, healthy, 6 pound rabbit.
There are many, many plants that rabbits can't eat because they're toxic or otherwise dangerous. See the link below for a big list of poisonous plants for rabbits. Also, don't think about feeding rabbits meat, dairy, grains, nuts, or "human" foods like chips, cookies, breads, crackers, popcorn, chocolate, sweets, pasta, sauces, etc. These foods are unhealthy for rabbits.
Here are the lists of fruits and vegetables a domesticated rabbit can eat:
Dark, Leafy Greens (good for a daily salad)
Treats
Make sure the fruits and other sweet veggies (like carrots) are limited. Don't feed your bunny fruits every day.
Rabbits tend to avoid plants in the nightsahde (solanacea) and onion (lily) families because they are not good for them. Pretty much everything else is fair game. They don't bother the corn leaves too much, but, they will eat the fruit (ears). I don't know about Okra, but I don't really have that much trouble with rabbits usually. My biggest problems are with deer. They eat everything, too, except the onions and nightshades. There is a poison in nightshades, called solanine, most animals avoid it. I t is found in the green tissue of this family. That's why it's not a good idea to eat green potatoes. The major plants in this family are potatoes, tomatoes, eggplant, peppers, tobacco and oddly enough petunias. Most are native to the New World.
These are all plants that are dangerous to rabbits. Eating this could cause anything from discomfort to pain, or even death. Ivy

There is very little vegetation that a hungry rabbit in the wild will not at least sample, especially when drought or cold has made food scarce. They'll eat just about any vegetable or grass they can find, various leaves, and flowers, and have even been known to strip the bark from certain trees. However, there are many plants that a rabbit will only eat as a last resort, when hungry enough.
Woodier, more difficult to digest plants are less likely to be eaten, and there is a long list of trees and vines that seldom see damage from hungry rabbits. There are also several plants that may even be poisonous and so rabbits know to avoid them. Here are some of the more common plants that seldom see damage by rabbits: Azaleas, Begonia Cacti, Columbine, Daffodils, Daylily, Four-O'Clock, Geraniums, Hyacinth, Lambs Ear, Marigold, Onion, Potato Rhododendron, Sage, Salvia, Sedum, Spider Flower, Spirea, and Yucca.
Jackrabbits like to eat plants such as alfalfa, clover, and cactus. They may also eat tree bark, sagebrush, and other types of grasses.
