Jan you are probably right there, I wondered if it was possible to really tell in the seedlings' first winter whether or not they were really dormant/semi/evergreen since seedlings may be more tender, and also whether the shadehouse would modify the effects. I have trouble telling the evergreens from the semis even in the well established plants in the garden. But the dormant plants in my area are easy to tell, there is no sign of them whatsoever till spring!
