I thought I'd post this here first before I try the Plant ID forum. I think I got this in a trade and, stupid me, forgot to label. I went back through all my completed trades and couldn't find it.
I hope someone knows what it is. I mainly want to find out if it's hardy or tender so I know whether to go ahead and plant it or overwinter it indoors.
Thanks to all.
I asked admin if the name should be changed from Athyrium to Diplazium in the PFs. They changed it to Diplazium. Has a ring to it, doesn't it?
I'm going to go ahead and plant it in the ground in very good soil. Can't wait to see how it does next year. I love it.
