I have given up on most of these sites. The plants recommended simply will not survive in my climate.
When I looked at the ATP member map, I found that there are no members gardening in my area of the state. Makes sense to me. With high summer temps with no rain and normally very wet winters, finding plants that can survive dry conditions and wet conditions gets complicated very quickly.
I do have wonderful drainage, but that has its pluses and minuses, too.
When I first started this garden, I was told to "plant what you love." The roses are doing fine, but finding other plants to work with them so that I don't have a mono garden isn't easy.
For me, it's a lot of trial and error.
