Gardeners' Notes:

I was surprised to see this plant listed as being hardy only to zone 5a. Here I am, in zone 3b, having grown this plant for 3-4 years with no extra protection and it seems to be doing fine in a well-drained, sandy soil. It is in full sun, but not in a warmer micro-climate. I am not absolutely sure of the cultivar, but they are all listed as hardy to zone 5a so I guess it doesn't matter!

I love the plant - provides a misty lavender blue appearance in late summer/ early fall when that color is always welcome. I do have to support the stalks, or they will flop over in the wind we have here.

I love this beautiful plant. It grows without extra water or fertilizer, and it sprouts babies in the spring!!

Beautiful purple flowers with silver/gray foliage. Smells wonderful. Draws bees and hummingbirds to my garden like crazy.

The leaves are deeply cut giving a very pleasing effect in grey-green. It is more floriforous than the type, with very long panicles of deep lavender blue flowers.
It likes a well drained poorish soil and plenty of sun.
