I have a couple of daylilies rated cold hardy to a half zone or so warmer than mine that I really want to grow. I was thinking about putting fist sized stones around their bases to hold heat from the day (we get a lot of sun.) Of course good mulch to within six inches of the base.
I'm open to any suggestions or if you want to you can sit back and chuckle at the cockeyed optimism of some daylily nuts.
