How nutritious are edible flowers?

I'm thinking of encouraging my kids, who refuse to eat veggies, to eat flowers if there is any nutritional value. I have roses, rose of sharon, snap dragons and peonies in my garden and of course dandelions in the yard. I thought maybe a little mixture of flowers and greens might get them eating a "salad". Will the flowers upset their little tummies?

I think the nutritional value isn't much except for rose hips which are rich in vitamin C. You eat the dandelion greens (unless dogs have been patrolling the yard) and they are nutritious like other dark leafy greens (good calcium!). Nasturtiums are edible. Violet leaves and flowers are edible. Johnny jump up flowers are, but not the plants. I think their stomachs will be fine because it is doubtful that they will find them tasty enough to make them sick.
Reply:How weird would it be if your kids went to school and starting picking up stuff in the gardens around the school and eating it. I'd be so embarassed...And the other kids would tease the heck out of them.

Dandelions and rose petals are edible but I don't know about the other 2. Pansies are edible too. Don't know about nutritional value though.
