Common Dewberry

trailing stem running along the ground for up to 15 feet. The stem has scattered hooked prickles, and is green when young, brown when older. The fruiting stems rise from the trailing stem, sometimes rising to 4 feet above the ground. The leaves are compound, usually trifoliate, with the three leaflets having a serrated edge. Northern dewberry's blossoms (and fruit) grow from stems arising alternately from the trailing stem. These erect fruiting stems may be from several inches to a few feet tall. Once the flowers of the northern dewberry are fertilized, drupes soon grow and replace each flower.[2] The drupes are a dark-purplish color and range from ½ inch to one inch in diameter.
