Ann thats good advice. I like hosta but am not a serious collector, sorry not good words on this foum.
Most of mine are un-named.
I just liked the way they looked. I was putting in an oder to I love hostas for some Heucheras (my collection addiction plant of choice)
I also bought Ice Age Trail and Allegan Fog hosta as suggested by CJ. I will give them a test drive. Most of my shade is take up with heuchera.
I read that the reason for the unstable forms is that the two leave color is two different tissues and that is way they revert.
What is the storty on a few that have three colors in there leaves?
