Learning Plant Identification
The best way to learn to properly identify plants is from a live person. Classes are available from herbalists focused on edibility and medicinal properties. Botany classes are available at most community colleges. Naturalists also know a lot of plant id. Check your local nature center or the Bell Museum. Don’t overlook people you may know in the community. Gardeners, mushroom enthusiasts, wild-food foragers and farmers, science teachers and biologists also frequently know a lot of plants.
There are also many facebook groups devoted to herbalism and plant i.d. where members can post photos and get help with identification from other members. There are even smartphone apps these days where you upload your picture and it identifies the plant for you (Warning: while fun and possibly helpful, never consider information generated from one photo sent to an app as positive identification of the plant in questions. Consider it a starting point. Do not harvest for food or medicine unless you are 100% certain)
As you become more skilled at learning to see the differences among plants, it becomes increasingly easy to learn them from books as well.
The most expensive book filled with glossy photos isn’t necessarily the best–especially if the book focuses only on the flowers. A line drawing sometimes captures the essence of the plant really well.
