Answer: Unfortunately, "Goodwin Creek" lavender is only considered winter hardy into zone 7. Your zip code places you in zone 6B or the colder part of zone 6 so they may have died. If you garden in a warm microclimate or very sheltered spot and the plants were growing in very well drained soil it is possible they might have survived. Lavenders tend to come into growth fairly late in the spring, and also may suffer winter dieback due to cold weather. You could prune off any deadwood beginning at the tips and working your way down the plants. If they are still alive they should recover and bloom for you this summer.
