One person’s weed-filled lawn is another person’s salad bar.
Perhaps the most familiar lawn weed of them all, the dandelion may also be the weed that’s most known to be edible. In fact, the reason it exists in the U.S. is that European settlers introduced it as a salad green. You can buy dandelion greens at some specialty food markets, but odds are, there are some growing, for free, a whole lot closer to you. They have a slightly bitter taste when they mature, so harvest the tender leaves that appear in early spring and in late fall, when they’re sweetest. The flowers are edible too and have a mildly bittersweet flavor. And eat them up! Dandelions have more beta-carotene than carrots.
