Virginia creeper (Parthenocissus tricuspidata) ready to turn these white walls green. Excellent vine for covering a shed, etc as it has adventitious roots (like boston ivy or creeping fig) and can attach itself directly to the surface.
Parthenocissus tricuspidata “Veitchii”, the Boston Ivy or Japanese creeper - Leaves are light green in spring, bright green in summer and turn purple-red in autumn. Growing up, these were on our fence. I remember that the little berries changed color too.
