We investigated an open field at the Biddeford High School. The sun was shining bright with no clouds in the sky. The air was dry and very cold with temperatures around 25 degrees Fahrenheit. Frost covered the grass and leaves of many plants. The plants we observed grew along a metal fence surrounding the track.
The stem grows in a zig-zag formation. There is one thorn at each 'joint' and small cluster of leaves. We think this species is the Japanese barberry because it has only one thorn at each joint, unlike European and American barberry which have one to three thorns at each joint.
Bright red berries will start to appear on this plant after September. The appearance of these berries is part of the seasonal change of the Japanese barberry.
The leaves of this plant are originally green and oval-shaped with smooth edges. They appear to be about two to four centimeters in length, however, our group did not get a chance to get an exact measurement. Also after September, the leaves of the Japanese barberry will turn purplish-red. The smooth leaves of the Japanese barberry separate the plant from the European and American barberry as they have leaves with toothed edges.
