Nr 1: The Dandelion
This is one of those weeds that is hated by almost every gardener but it is also one of the most common and usefull wild edibles. The entire plant is edible.. The leaves can be picked and put in a salad, young leaves taste best. You can dig up the roots, roast the on a fire and after crushing them it can be used as a coffee replacement. The yellow top can be picked and eaten directly which has a sweet taste. These also make for a great tea.
Nr 2: Cattail
This is one best plants to stumble upon if you're out in the wilderness, not only is it edible, the pollens at the top are great firemaking material. The parts the can be eaten are leaves that can be cooked and used as a salad. The roots are also edible cooked or raw.
Nr 3: Plantain
Another weed that can be found in gardens, parks, farmlands, well.. everywhere.. The leaves are edible both raw and boiled, and the seeds can be harvested and eaten as well. In addition, plantain is a great plant to know for treating minor wounds and insect bites. Simply chew up several leaves and apply to the wound, repeating as desired.
Nr 4: Stinging nettle
A very niticious plant that needs to be cooked or steamed for obvious reasons. The cooked leaves taste somewhat like spinach. Dried leaves make for a great tea. It turns out that people also used to make beer, coffee and flour from nettles. It also has medicinal uses, for example nettle tea purifies the blood.
Nr 5: Clovers
There are many types of clovers including the red and white clover. The leaves and young flower heads are edible cooked and raw and are great for salads and soups. Odd enough dried leaves seem to taste somewhat like vanilla
Nr 6: Grass
Didn't saw that one coming did you? But in fact all grasses (and there are a lot) are edible. Edible, in this case realy means that you can eat it and that it's healthy, it does not mean it will taste nice. But because it is edible and found anywhere it is one of the greatest survival foods there is. It can be a little rough on the stomac so it should better be cooked.
