Erysimums...perennial wallflowers. I have some lovely ones in my scented border, and in a mild winter they would still be flowering. But this cold winter has done for them. They look just like any other perennial now...all white and dormant. They are about a foot tall and all of them are flopping over. should I cut them back now? And how much? Thanks! :)

I'd wait until March but mine usually stay in leaf. In the past they have died when they have gone all white. I hope yours haven't gone over :o(.
