I don't know a whole lot about nature magick. But i am pretty sure this when people who practice magick that involves nature, Such many things can include flowers, plants and herbalism. Nature magick includes things that come from nature, including ingrediants that are used in spells or rituals. Some people use their energy to give back to nature in return for helping them in their ritual work. Some people include things spiritually like animals to help them in their ritual work or spell creation.
