I thought I'd posted this thread already, but now I can't find it, so pardon if this is a double. It could be the heat defeating me.

I was mentioning in another thread how I walked away from buying hostas at a landscaping place that just didn't seem to have reputable suppliers (and after Steve's thread, I'm doubly glad, because the Plant Group is definitely a name I've seen on their perennial pots).

Anyway, here is Irish Luck. Is this frost, heat, HVX, all of the above?
