Parthenocissus tricuspidata Veitchii (Boston Ivy)

Noted for its smaller leaves than the species, Parthenocissus tricuspidata 'Veitchii' (Boston Ivy) is a very vigorous, fast-growing, deciduous climber boasting mostly ovate or three-lobed, rich lustrous deep green leaves, 6 in. wide (15 cm), turning brilliant shades of crimson, scarlet and burgundy in the fall. Usually hidden by the foliage, greenish-white flowers appear in the upper leaf axils in late spring to early summer. They give way to round, fleshy, blue-black berries, visible only after the leaves have fallen and if the birds have not devoured them. Semi-evergreen in mild winter areas.
