Vitaceae

Grape Family

Virginia Creeper (Parthenocissus quinquefolia). Some of the brightest and purest reds in the fall come from Virginia Creeper, or Woodbine. It is a beautiful vine all summer, but when its glossy dark green leaves turn fiery red in fall, it can light up whole tree trunks in the woods. The five leaflets are distinctive (and give the vine its species name quinquefolia); no other woody vine in our area has leaves like these.

Vitis aestivalis

Vitis riparia

Frost Grape (Vitis vulpina). These are the grape vines that take over whole lots and smother large trees. When they get to tree-smothering size, they produce thousands of these little grapes, which are intensely flavorful and quite tart. They sweeten a bit after a frost. The grapes hang on into the winter; these were hanging on a huge vine in Beechview in late November. Below, a typically monstrous mound of Frost Grapes on the South Side Slopes.
