I was wondering what has been your best performing plant this year (or last since it's still early in the season). I love hearing about people's favorites!
Mine would be "jack frost" brunnera. It's a great shade plant (I feel like there aren't a ton of choices for shade) and it leafed out and is blooming before my hostas were even out of the ground- it was actually one of the first perennials that up in my zone 5 garden. The foliage is beautiful and looked great all season, while my hostas were eaten by slugs. I'm definitely getting a few more this year.
