>>2200391>Am I missing any important ones?You're missing almost all of the important ones. You dont say where you're from but it seems like eastern north america.
If you've ever heard of the 80/20 rule, it also applies to plants. 20% of plants will provide 80% of calories. Same ratio for things like vitamins, minerals and other nutrients.
So heres a list of the most important plants in each category IMO that applies to the eastern US. This is based on abundance, ease of gathering/processing and nutrient content in my experience in the southern parts of the northeast.
Nuts:
>acorns>hickory>bitternut hickory (for oil)>black walnut>hackberry (extremely underrated)>lotus nuts>butternut>hazelnut>less important is beech nut due to small size and irregular fruiting. Still important in some places. Seeds:
>wild rice>goosefoot seeds>amaranth>golden clubUnderground storage organs:
>Parsnips>Groundnut>Sunchokes>skunk cabbage>lotus>wapatoOther:
>Maple/walnut/birch sugarThose are the calorie crops that will supply most of your calories. The following are those plants that will supply most of your micronutrients while some also supply some calories.
Vegetable:
>Wild leeks>Nettle (wood and stinging)>basswood>pokeweed>violets>watercress>milkweedFruit:
>apples>persimmon>blueberry>cranberry>pawpaw>wild plums (american, canada, beach, quapaw etc)>chokecherry>autumn olive>viburnum berries (hobblebush, wild raisin) very abundant in some areas.Note how bramble berries arent in the list. Thats because they are small, delicate and thus difficult to gather in large quantity. So not a staple fruit. In some cases, especially blackebrries, they can be very abundant in some areas and can be a preserved and used as a staple.
