Hosta 'montana Aureomarginata'.
Someone else asked for a division a while back. This gets 27 inches high & 60" wide. I'll let you know, I wanted a daylily from a lady and she canceled my trade because I only had one plant she wanted, at the time I told her Montana was unavailable. I will try to divide it and send you a piece also because this is a great Hosta for the south, I read this on Hosta's Direct:
H. longipes, H. kikutii and H. montana cultivars and all of their variants and hybrids would be good choices to survive extremely dry and hot conditions.
Hey, I do not read that very often about a Hosta!!
