Virginia creeper ( Parthenocissus Quinquefolia)
Description
Parthenocissus quinquefolia, known as Virginia creeper, Victoria creeper, five-leaved ivy, or five-finger, is a species of flowering plant in the grape family, Vitaceae. It is native to eastern and central North America, from southeastern Canada and the eastern United States west to Manitoba and Utah, and south to eastern Mexico and Guatemala. Parthenocissus quinquefolia is a prolific deciduous climber, reaching heights of 20–30 m (66–98 ft) in the wild. It climbs smooth surfaces using small forked tendrils tipped with small strongly adhesive pads 5 mm (0.20 in) in size. The leaves are palmately compound, composed of five leaflets (rarely three leaflets, particularly on younger vines, and sometimes seven) joined from a central point on the leafstalk, and range from 3 to 20 cm (1.2 to 7.9 in) (rarely to 30 cm [12 in]) across. The leaflets have a toothed margin. The species is often confused with P. vitacea or "False Virginia creeper", which has the same leaves, but does not have the adhesive pads at the end of its tendrils. It is sometimes mistaken for Toxicodendron radicans (poison ivy), despite having five leaflets (poison ivy has three). While the leaves of P. quinquefolia do not produce urushiol, the sap within the leaves and stem contains raphides (needle-shaped crystals of calcium oxalate) which can puncture the skin causing irritation and blisters in sensitive people. The leaves sometimes turn a decorative bright red in the fall. The flowers are small and greenish, produced in inconspicuous clusters in late spring, and mature in late summer or early fall into small hard purplish-black berries 5 to 7 mm (0.20 to 0.28 in) diameter. These berries contain toxic amounts of oxalic acid and have been known to cause kidney damage and death to humans. The berries are not toxic to birds and provide an important winter food source for many bird species.
