Don't jump to any conclusions yet. Your plants might still be fine! Perennials and shrubs enter "dormancy" in the winter to conserve energy, which is basically one long nap. Some plants are still sleepyheads when spring rolls around, and are slower to leaf out in the garden.
Butterfly bush(Buddleia) is notorious for hitting the snooze button. So,we aren't surprised when we are frequently asked, "is my butterfly bush dead?" We know it's hard to be patient with all the excitement of spring, but that's exactly what butterfly bushes need. Give them a few extra weeks in the spring to push out new growth. In cold climates, you may have to wait until June!
