You should also visit the Montana Plant Life page to find lists of edible Montana plants grouped by the edible part (e.g., berries, seeds, leaves, etc.).  Not all the plants in their database are native, but they do have a native plant list for comparison and you can always check the plant against our Native Plant Database which contains only plants native to North America.  If you want to find out if the plant grows in Sanders County, you can search for the plant in the USDA Plants Database using its scientific name.  When you reach the species page, click on Montana on the map and it will give you a map showing county distribution of the plant.   For example, for Sambucus racemosa (Red elderberry) you can see by its distribution map that it occurs over most of the United States and Canada.  If you click on Montana on the map, you will see that it occurs in Sanders County on the Montana distribution map.

You can also read the answer to a previous question about edible wild plants in Montana with a list of suggested books about edible wild plants tht occur in Montana.  You can also see a list of edible and medicinal plants available for purchase from Blackfoot Native Plants.  Here are a couple of edible, native herbaceous plants from their list that grow in Sanders County:
