Some Practical Advice on Cooking with Flowers

Even if you know a flower to be edible, such as a rose, do not use it for culinary purposes if you think it may have been sprayed with harmful substances such as pesticides. Flowers purchased from high-street florists or supermarkets should not be used in the kitchen, as these will almost certainly have undergone spraying and other chemical treatment. You should only eat bought flowers if they come from a florist who can guarantee that they have not been sprayed.
