I expect your plant was just taking some time to adjust to its new location. If I'm correct it should look a lot better this year. The roots should have grown well since you planted it very early last year. It wouldn't hurt to give it some fertilizer to jump start it but try to give it compost or something else that won't burn it. I think the amount of sunlight your plant gets shouldn't be an issue. I have most of my plants in the backyard and they probably get 40-50% sun and do just fine.
I don't know about that cultivar but some daylilies do take 3 years (or longer without lots of fertilizer & extra water) for me to see them bloom. But if the plant doesn't seem to get better despite added attention I'd think about replacing it. I bought a peony from Costco a few years ago and it grew ok but it did take about three years for it to give me a bloom. Others I bought from different places bloomed a lot quicker and better. Check out the green pages here for some other vendors.
