I just checked my plantstep flower program and I grow nearly 70 dormants. I have lost some dormants and I still have a few that really struggle. Most of them do very well, and a few of them are some of my favorites and best performers. One I really like but that I just can not get to grow well here is 'Smoky Mountain Autumn'. So at best I suppose it is a matter of trail and error. But, I certainly would not rule out growing dormants here in my zone 8b garden. Before you buy a dormant you might want to check here on the forum and ask how it does for some of us in 8b.
