These extensions from the vine's stem attach themselves to whatever is handy, using a suction-cup- like adhesive disk at the end of the tendril that sticks to any flat surface

14. The leaves are compound, with leaflets arranged like the spreading of fingers of a hand from one central point on a stem. Three to five 4 inch long leaflet makes up a single leaf. Virginia Creeper blooms from May into August, the flowers generate small Blue-Black fruits by September
