Heaths or Heathers that won't need winter protection?
I'm an aging gardener looking to ease up on the work in very large ornamental beds. I think I have ideal conditions for heaths and heathers (sandy, acid soil), but although I am a very experienced gardener, I have never grown heaths or heathers and know very little about them. I've only begun to learn something about them, and what I've read suggests that many people cover their heaths and heathers in winter, not something I want to add to the yearly work.
Can you suggest some varieties that I won't have to cover? I'm open to all sizes and foliage colors and am not fussy about bloom time.
