Our native vines and shrubs may be easily identified from the following descriptions. Some perennial herbs are included in the list, plants without woody stems, which therefore die down every year, but whose roots continue to live through the winter and send up new stems in the spring. These often have the appearance of true shrubs. An herb dies down, stem and root, to the ground every year, and must be reproduced from seed. A shrub has woody stems and does not in any part of it die down every year.
