My Evelyn hebes( I have 3) were planted last November . 2 in rather shady spots and one in full sun. I didn't know they were frost sensitive and didn't protect them. All three have brown dead leaves now and look pittiful! Is there anything I can do ( remove the two from their shadier place??) And can I hope for revival??our winter was unusually harsh!! I am in western Switzerland next to lark Genèva( pretty mild climate) Tham Nk you for your reply! Christine sefolosha
