FLS has lovely deep green foliage and non-stop lavender blooms that fade to a beautiful silvery color, and quite an upright growing habit which is fine with me because I didn't want it to sprawl anyway. I love the fragrance, it reminds me of the Blue Moon rose my mom grew when I was a kid. I will see how it does over the winter before I have an opinion on hardiness. I don't spray and it has been very healthy for me. My soil type is acidic, zone 4b and altitude of 5000ft.

Editing to add that it survived my zone 4b winter with about five inches of good cane coming from the base. I'm happy with the hardiness seeing as I got it as a zone pushing experiment.
