I found that it is a dormant here in my zone 5 garden. Not in an ideal location ( along the drip line of a maple tree) it does okay. The blooms open early in the morning and look good by the end of the day, this could be due to the shade it gets during the afternoon heat. Steady increase, and not a prolific bloomer. Once again probably due to its location. It is hard to find something that does well by this tree as it stays so dry, so Pandoras Box is willing to bloom here and looks good. I am going to leave it where it is.
