2016 update - Aug 5
I divided this one at the end of 2015 and sold off most of it, but one division stayed in the back of my veggie garden and, for the first time, it went through a whole season w/o becoming lace from the slugs. Still not really sure whether I'll keep it long-term though as there are several very good newer green hostas and I don't have space for all of them.
