I seem to have a number of aquaintances who believe plants "talk" to them about their edible and medicinal properties, whether they identify a plant or not. Their routine includes closed eye exploration of the scent, feel, taste, sound of the plant rubbing on one's cheek and hand, and then open-sensed [including intuitive and spirit based] appreciation of the plant as a whole and how it fits into its environment. Me, I like plant guides.
