There should be some spring left in the branches rather than a dead "crunch." My lavender never lasts a long time...some where in the 5 - 10 years max. Perhaps this hard winter - and it was hard! - was the killing stroke for aging plants. But wait until plants regreen before writing them off. You've got nothing to loose and much to gain with a little patience.

English types like hidcote and munstead are cold hardy.
