    Note: This species combines what were once considered two distinct species, the European cranberry bush (V. opulus) and the American cranberry bush (V. opulus var. americana). Most references still refer to the American cranberry bush by its old latin name, V. trilobum. The two cranberry bushes are difficult to distinguish, and for the purposes of this project, you don't need to tell them apart. Simply choose V. opulus on the data form.

    Leaves:

    • Deciduous
    • 2 to 4 inches long and wide
    • 3 lobes
    • Pubescent (hairy) veins on underside
