Prunella grandiflora 'Pink Loveliness'
Just wondering if anyone has grown this plant? I've been finding a wide variety of information about it in different web sites. Unfortunately none of them seem to agree. I've seen hardiness ratings stated as zones 4-8, 5 - 8, and 6-9. I've read that it spreads slowly to about 16 inches and another site states that it requires frequent division to keep it under control. The height range has been given as 6 inches to 30 inches. I'm guess the variations may have something to do with growing location. Anyone in good ole MN familiar with it.
