Sabrina,
I grow Always Afternoon, and live in zone 8b, in South Carolina. This daylily does well for me, and multiplies at an average rate; usually a couple of new fans each year.
I have certain daylilies that seem to pout in some garden spaces, while others do just fine. If I have one that pouts, I try to leave it where it's at for a couple of years for it to adjust. After a few years, if it still doesn't do well (and others around it do), I'll try it in a new spot. If that doesn't work, I find it a new home
