Hi I have a very big south facing red brick wall. It is a church so it has 4 large gothic windows. The wall is roughly 60x20 feet. I would like to build a green wall so that it can help with cooling in the summer and heating in the winter . My questions are I want the leaves to drop in winter( so that the sun can heat the wall) but I don't want the plant to have to re-grow every year. I believe I would want a deciduous ivy correct? What is the fastest growing deciduous ivy that drops its leaves early say late november and that doesn't have a big woody root system that might damage the foundation Can ivy damage the wall if it is let to grow on the wall or should I grow it off the wall on lattice say 1 foot away? Will it actually make the wall heat more is it is on it( no air movement) any option for off wall lattice for such a big wall best distance from the foundation for off wall growing many thanks
Ivy is evergreen, there's no such thing as a deciduous ivy. Your best choice would be Virginia Creeper (Parthenocissus quinquefolia) or Japanese Creeper (Parthenocissus tricuspidata).
Thanks Michael I doing some research on the web some vines were referenced as Deciduous broadleaf..being a newbie I took their word for it.
