Proven Winners 'Empress Wu' Hosta!
I found this on facebook and was impressed enough to share. I don't live in Hosta Country, they're usually tiny plants compared to this one, and don't usually survive in our heat, though mine has come back from dormancy, much to my surprise!
Anyway, I couldn't believe at first that this is really a hosta, I had no idea they get this large!
