MILTA. Those are some beautiful pics you got going on there. I have always admired liatris, but never have put any stock into my gardens, I should, as I think they are so pretty. If there are no bees on the hyssop, I would think there is something else they are loving more. My hyssops are covered in bees, all the time that they bloom, which is well into September, or later. My cultivar is 'Blue Fortune". I take cuttings so the plants stay true to the parents. Keep those pics coming, they are beautiful. Have the most wonderful and awesome of these days. Cindi
