H. 'Kifukurin Ko Mame'
All the way from Ottawa, ON, this is a welcome addition for 2011. It's supposed to be quite vigorous and I look forward to having it in various locations as an edger over the next few years. It somewhat reminds you of 'Lemon Frost' except for the wavy edge to the leaf.
What I received in 2011 did end up getting divided. Here's one of those divisions in early May 2012.
