It's definitely one of the most popular, for certain! I think, at least in my garden, it is only topped by the Joe Pye Weed (Eutrochium)...it thrums with activity while blooming...I've never seen anything quite like it!
I haven't grown that yet...I will be sure to give it a try.
One of my most favorite perennials! Nice shots, man!
Same here although I probably say that about 30 different plants :)
