Perennials destroyed by spring frost. Will they come back?

Question:

The newly emerged growth on several of my perennials has been destroyed by a late spring freeze. Will the perennials come back?

Answer:

Newly emerged perennial growth is susceptible to damage from freezing temperatures.  While freezing temperatures may have damaged or destroyed the new growth, the roots and crowns of healthy, well-established perennials should still be alive.  The damaged perennials should send up a second flush of growth in a few weeks.  Good care (for example, watering weekly during dry weather) this spring and summer should help the perennials recover.
