Plants can be categorized as useful, edible, medicinal, or a combination of those three. Some of the most useful plants to learn are typically the ones that combine all three. With so many plant species growing in so many different environments during different times of year, it would take a person several lifetimes to learn them all.
This course is designed to narrow that list of tens of thousands into a handful that are most useful in a survival situation. The plants learned will be highly variable based on location and time of year.
