Mike, I love your greenhouse! I like Well Sweep too but sometimes their plants are not groomed well so they don't have a good shape. Still, I like to visit every other year or so.
This year, I didn't bring in 'Gray Lady Plymouth' in soon enough, so I lost those two. That one I will replace.
It would be hard to tell what kind of geranium that cascading type is. Once it flowers, we might be able to suggest similar ones but couldn't say for sure which one it is.
