Shores of Time is one that has done poorly for me. Everyone else I talk to says it does wonderful for them. This will be my third summer with it so we will see what happens this year. I think that sometimes some cultivars just take awhile to settle in. Spiney Sea Urchin is another one that has done nothing for me. This will be its third summer here also. I sure hope that one does better this year and at least blooms for me. It took 3 summers for Gram's Dream to take off. I almost got rid of it and something just told me not too. Boy am I glad I didn't now because it's first bloom was stunning.
