This is the wall I want to have flowers that cascade. Temps range from 10* to 95*. This will be mostly in full sun. I took this picture today, and it is raining so it may not be real clear.
I am interested in the following flowers but open to other suggestions. I would like for you to comment on the flowers I have listed as to whether they would work in this medium or not.
1. Lobelia compacta
2. Campanula carpatica
3. Aureria saxatillis (paticularly "Citron")
4. Iberis sempervirens
5. Aubrieta
6. Nepata xfassrenii I have neighboring cats and I am a big birder so don't want to draw cats to my yard even though I love the looks of this plant and feel it would with stand the hot temps.
