I got Strikingly Dramatic late this summer from Maryotts - and got some beautiful reblooms from it this fall. It will be interesting to see how my 2012 Maryott's survive. I am sure a lot will depend on how cold it gets here, so far we are pretty warm for December - although we have been down to almost single digits this year too. I have my daylilies mulched pretty heavily with leaves - but now I am worrying because the weather has been too warm - and the heavy mulch may not be so good this year.
But you are correct, you may find that your weather zone may limit you to the hardier plants. Did you contact Maryott's about your problems?
By the way, which direction does your hillside mostly face? North, south east west? That may be part of it too. 4b is a pretty cold zone. ~Jan
