I have had thin Man since 2010. I live in Canada zone 5a. It has survived our winters although the last 2 have been milder than usual. It is on the western edge of a garden on the front lawn of our farm. The wind howls through there all winter long and not much snow stays. I do leave all of the plant there for the winter to hold what snow we do have so it is "mulched" in a way. It also gets some shade from the maple behind it. I would maybe get more blooms if it got more sun. But I love it and always take photos of it. It is so photogenic!

Grows well here and seems quite hardy, but not a really fast multiplier.

I can't tell you about the north but here in North Alabama, it does wonderfully. I love this daylily....Ellie

I just went and checked some stats for my Thin Man. I purchased it in August of 2010 which I have never done before or since! Usually only spring planting around here. There were 2 nice sized fans. In Sept of 2011 there were 3 fans and 2 scapes. Right now there are 10 fans and 8 scapes which I think is decent growth. There were a max of 11 buds on any scape.
By contrast Velvet Ribbons, which is right beside it, hasn't done as well. I bought and planted it in May 2011 when there were 3 fans and 3 scapes that summer. There are still only 4 fans and 4 scapes this year. I really do love the bloom though and confess to hybridizing with it!
