I'm in the process of moving some wild daylilies from the side of our yard to a bank that slopes to the road in front of our house. I know they will fill in quickly over the next few years and I think they will look beautiful during the spring and summer; however, I am concerned the bank will just be bare during the winter. I've never really noticed what a thickly-planted daylily bed looks like in the winter.
Is there something that will grow interplanted with the daylilies and provide some winter - if not green - cover? Will the dead stalks of the daylilies be enough to cover the bare ground?
