(As far as I can tell this is the same daylily). Do any of you gardeners grow it successfully in zone 6A? I read 2 comments from people in zone 5B that said it wasn't doing well there, and I don't want to waste the time, money or space if it's too tender for me. I would greatly appreciate hearing your advice or experience with this one. I really wanted a true pink daylily with a deeper pink edging!!

I do not grow the plant, but there seems to be no registered daylily under the name of 'Beautiful Ballerina', but 'Ballerina Beautiful' is a registered plant by Carpenter-J.
Sorry I am not much help on how the plant grows in your zone.
