They would need to keep Clivia in a greenhouse. Not having any experience with cold winters myself, I will not suggest what to plant in shade to get pop color. But I do suggest trying the Brent & Becky catalog "Bulb Finder" tool. You can select zone and shade and several other parameters to get suggestions. I searched for zone 5, full shade, and blue and got 5 Scilla suggested. Not much for the other colors. So I see why this question came up. - Gastil
