Hello. this is only my second sping with my plants, they were bought last spring. The people at the garden told me that the red stem parrot feather were hardy and would survive the winter if I lowered the pots witch I did. I brought them up about a week ago and am wondering if the made it and how long before seeing growth. Right now they look like someone sat on them. I left about 3-4 inch stems when I cut them back.They are not mushy and feel firm, but the lush green part seems to be gone,is this normal.I live in Delaware. Thanks
