Plant: woody vine, climbing or sprawling

Flower: small 5-parted flowers; infloresence branched into two (sometimes three) more or less equal subdivisions

Fruit: grape-like, dark blue, ~ 6 mm; infloresence branched as above

Leaves: alternate-compound; 5 palmate leaflets, 6-12 cm; with sharp end points and sharply toothed, shiney above; bright red in the fall

Buds & Twigs: pith white; climbs by tendrils which do not end in adhesive disks; tendrils absent after every third leaf

Bark: tight

Habitat: moist soils at edges of woods, fencerows

Range: Quebec and New England; south to New Jersey; west to Manitoba, Wyoming, Texas, Utah, and Arizona

Similar Species: Virginia Creeper, Parthenocissus quinquefolia, is also found in our area: Its leaves are very similar but most of the tendrils by which it climbs end in disk-shaped adhesive pads; the flower/fruit clusters have a central axis rather than being subdivided; it also has leaves with duller upper surfaces.
