Nice blue colour, but very slow to grow - did not grow much during the first year planted it. In the spring it showed no signs of life when other perennials emerged. I thought it had died, so I bought a "Blue Angel" to replace it. When digging, much to my surprise, the Big Daddy was still alive and just then sending up shoots. I carefully dug it out and replanted it under a crabapple tree. We'll see if it survives.
Must be neutral on Big Daddy for now. I just received it from my son who had it in 2 hours of afternoon sun everyday. It did not like it at all. The leaves started burning and did now grow much at all. I am now planting it where it will get very little sun, if much of any and see if I can get it to grow. When the say partial shade to full shade, they mean mostly shade to full shade. It is a beautiful blue green (or was until sun got to hot). The sun took almost all the blue out and burned the leaves
Am really anxious to see how it does under the pine trees.

I'm amazed at how quickly this plant has grown for me - I could hardly get it out of the pot fast enough. I have very big slugs here in the Pacific Northwest and they are voracious about eating hostas. But, for some reason, this seems to escape relatively unscathed. I'm looking forward to dividing this and putting it in several places in the garden.

Large, impressive, slug-resistant with blue-green foliage. Leaves are 15" long by 10.5" wide; rich, blue-green color changing to deep green by late summer. Thick top and underside bloom; blade broadly ovate with deeply lobed bases; often cupped with intense corregation and a thick substance.
Flowers mid-June into July are near-white in dense clusters on 24" to 32" scapes.
