Wild plants that are edible: (this is about the only non-useless info on here...)

• Burdock (very bitter)
• Dogwood berries, but not the plant (the berries taste like burdock)
• The inside bark of a cottonwood tree
• The white inside part of a cattail (tastes good! Sort of like a really mild cucumber.)
• Watercress (sold as a delicacy in restaurants, but I don't like it much, it tastes like a really spicy radish)
• Poplar bark
• Anise (Very good, if you like black liquorice!)
• Dandelions. The leaves make a great salad, and the roots can be roasted and ground into something kind of like coffee.
• Any kind of mint, which is recognizable from the smell
• Wild rose hips, but not the plant (the hips are high in Vitamin C and are an ingredient in many teas.)
• Thistle (Scrape the thorns off, duh! Eat the leaf or the inside of the blossom.)

• Some berries, including strawberries, raspberries, chokecherries (too much pit to be worth it), currants (TART!), serviceberries, gooseberries (green and stripy and TART!), purple elderberries (red ones are poisonous), etc. Don't eat sumac berries, they are poisonous!

Wild plants that are poisonous! (some more non-useless, a disgrace to the site)

• Nightshade, recognizable by its purple and yellow flower
• Dogwood
• Houndstounge
• The wild rose plant, not the hips
• Most mushrooms. Don't eat any unless you know what you are doing.
• RED elderberries. Purple ones are okay.
