My landscape designer has proposed the following:

12 Lamium 'Orchid Frost" 1qt

3 Geranium 'Brookside' 1 gal

3 Polemonium 'Stairway to Heaven' 1 gal

for the natural area under heavy shade provided by several ash, cherry and a redbud tree. This area is quite dry because of the tree canopy. The area is next to a large stone patio project that was completed last summer. I have a lot of hostas in other parts of this area. Do you think this is a good combo? Will it thrive in my conditions?
