I have had this plant since 2010. Somehow it survived the vole attack of 2014. The voles came right through the space between this plant and Goodness Gracious about a six foot gap and killed everything except clausa. I replanted last season with many of Chris's plants - added some new ones that I had never used before.

And the 2014 season:
And here is the group early in the 2015 season when I started to fill in the vole damage. Sara's Sensation is on the left/middle of the photo. Goodness Gracious is center/right in front of the two trees. Jubilee (new) is front right with Key Lime Pie (new) center.
