There are flowers you can eat, but you don't necessarily know which ones are non-poisonous. Nobody wants to die a death by consuming random flowers. It's almost embarrassing. So here's an Edible Flower Seed Kit from Sarah Rainwater. At $50, each kit comes with four different types of seeds, soil, and a pretty wood-and-glass planter, with some instructions. The flowers selected are easy to grow, and you won't be obliged to chomp on them if you just want to let them sit by your window sill looking pretty. However, they're only available in the U.S. [Etsy]
