Will be constantly added to, every time a plant is eaten, it'll be added here.

Cattails

Young cattail shoots and roots are also edible parts of cattail plants. The young shoots are found once the outer leaves are stripped and can then be used stir fried or sautéed. ... The tough, fibrous roots can also be harvested. They are then dried and ground into flour or boiled down with water to separate the starch

To prepare a cattail root, clean it and trim away the smaller branching roots, leaving the large rhizome. You can grill, bake or boil the root until it's tender. Once cooked, eating a cattail root is similar to eating the leaves of an artichoke – strip the starch away from the fibers with your teeth.

Remove outer peel, can be eaten raw, doesnt have much taste kinda feels pastey and melts in your mouth.
Boiled- looks kinda like pasta when it boils, smells like potatoes, still kinda melts in your mouth but is also chewy, has a good buttery/carrot/potato flavor, can possibly be used to make a soup because it leaves a creamyness to the water.

Pine needle

The needles from most coniferous trees, Pine, Fir, Spruce, and Hemlock are loaded with vitamin C and other nutrients. You can use it for tea, or you can grind it up and use it as a seasoning for cooking. It has a piney/citrusy taste and it smells good.
