I don't live in the US, but I don't see why it wouldn't be useable. It's not hard to spell or pronounce. It is a flower name and many flower names are common so I think it would fit in fine with those, and I'm pretty sure people would know that it's a girls name.
I like it. It's a little bit cutesey but I still think it's nice. The only problem is when I type it I sometimes accidentally type "poopy"!
