Hi all,

I see a lot of debate whether hardy, semi-dormant plants need light in winter. I know most hardy, dormant plants do not need light, such as deciduous plants or a juniper could survive covered in a snow mound, but there are plants that comes from more temperate zones that people describe as semi-dormant in the winter, such as some types of boxwood. Do these need any light in winter? What about Azalea / Rhododendron?

I mostly have tropicals, but started collecting some hardy plants (by accident - gifts from others) over the last few years, which I keep under my storm doors, which is probably mid-30's to mid-40's all winter. It gets little to no light except around small cracks. I'm thinking of adding a few more hardy plants and wasn't sure if certain hardy evergreen broad-leaf plants would survive there.
 
Unless a plant is buried under snow in it’s natural habitat it would be safe to assume it needs some light to fulfill its dormancy requirements.
