IVY is invasives and are out of control and smothering our trees. Please remove ivy from your list. There are so many great native alternatives - aster divaricatus - christmas fern plus many others - tiarella cordifolia - pachysandra procumbens (allegheny spurge) Check out some university agriculture extensions. My suggestions were for the mid-atlantic area. To determine native species by area http://bonap.net/NAPA (Biota of North America). Thank you for your consideration.
