I'm trying to find a tall, columnar plant/shrub that will grow in containers in full shade, zone 6b. The containers are next to a new brick wall that has effectively blocked most direct sun. Last fall, I planted Sky Pencils (about 4-5 ft. high) in large containers. They seemed to do well initially, but we had a terrible winter here in the NE. They don't appear to have survived. I plan to do caladiums in summer, but want a tall, columnar shrub accent in the containers for year-round. I've looked at some of the new columnar euonymus (like Green Spire) but they don't seem suited for the full shade. Any suggestions would be appreciated.
