Hello, I had niobe for quite a few years and it was spectacular, but it up and died 2 years ago for no reason. I now see Rebecca at a local garden store, and compared the two for color. It seems they are about the same color, but Rebecca looks to hae bigger flowers. The niobe did get wilt most of the years, but if I cut it off early enough it would grow back and flower a little more later on in the year. I'm in zone 5.

Any comments which one you like better and/or is more hardy. I don't want to lose this color again. its special.
