Some flowers literally look good enough to eat: Nasturtium, borage, violets and other blooms have found their way to the table at restaurants and even in the homes of adventurous cooks. But there are some flowers that simply must remain in the vase, as they're extremely poisonous. And they don't all come with warning names like "deadly nightshade." Irises, calla lilies, sweet peas and potato flowers are all lovely to look at, common decor at weddings or in the garden (or at garden weddings), and completely dangerous if ingested.

This chart is a list of the most commonly-known poisonous plants and flowers to avoid while selecting edible flowers. It is not complete by any means, so just because you do not see it listed here, do not assume it is safe to eat. Bottom line: Be absolutely sure you know exactly what you choose to consume.
