Start with the number-one habitat for wild edible plants â your lawn. Any place that is regularly cleared is loaded with weeds such as dandelion, chickweed, plantain, wild onion, violets, wood sorrel, henbit, clover, dead-nettle and sow thistle â all of which are 100% edible.1  Start with grass. 2  All grass is edible. If you want to avoid the stems, and eat mostly the new growth, pluck off the tops and eat those. 2  Wood Sorrel (oxalis spp): The whole plant is great raw-it has a nice acid flavor, refreshing. 3  The flowers of the cosmopolitan weeds are yellow, but many varieties grow in the wild with pinkish flowers.
