Saw this at Wright's Nursery on 44th avenue last year but didn't buy it. Went back this year to get it. This is Self-heal 'Bella Blue' aka prunella. It has been a lovely little performer. It has bloomed all Summer and is still blooming, no deadheading whatsoever. It gets these little purple flowers on a cluster. Grows low to the ground in a small clump (about a foot wide so far). Would be perfect in a rock garden. I have it in full afternoon sun and it seems to be quite happy.
