Many people grow flowers to brighten up their gardens, but some blooms not only look beautiful, they're also edible. If you want to add a floral touch to cakes or homemade cocktails, here are five edible flowers worth planting. Nasturtiums are a great addition to your garden as they are fast-growing and can be a useful alternative to putting pepper on a salad. Pansies come in a variety of colors, and while they will give your garden a vibrant color, they are also sweet, which makes them a great addition to any baked goods.  If you're looking for the perfect garnish for a soup or risotto, calendula offers a peppery kick and a splash of color to the meal. The eastern redbud boasts a tangy taste, which will give your salad the perfect twist, and can also be grown in containers indoors. Marigolds have long been used to color rice or flavor tea, and they're great sprinkled over summer salads too.
