I let dandelion grow unrestrained in my little garden. My neighbors probably do not like it very much, but every single part of the plant is edible, and very good for you. I like to think that it is also good for my soil, by purifying the soil of toxins just as it purifies our bodies. It is also one of the earliest spring flowers, and attracts many bees and butterflies. And it is beautiful! I don't know why it has such a bad rep. It's one of my faves.
