Is my Butterfly Bush dead?
On a whim last year I planted a butterfly bush in a protected SW corner of my house. While the rest of my shrubs are coming alive and showing signs of coming back the butterfly bush seems to be dead. How can I be sure? I'm ready to yank it out.
I didn't do anything last winter to protect it. Is there something I should do to protect future butterfly bushes (or shrubs that aren't quite hardy enough)?
