All plant species listed are perennial.  All have been reported to be edible in some form.  However, please do your own research before consuming any plants listed here, as it's better to be safe than sorry.   Additionally, edibility does not account of quality or taste.  I would also encourage people to cook anything, where there may be any possibility of toxins existing in the plant's raw form.  I hope you find this list informative.  I will continue adding to it, as I find more.
