Good morning Teresa
I have had good luck with Cheyenne Spirit. I'm on year three now. Pow Wow Wild Berry has been a very hardy Echinacea for me.
I no longer buy Columbine. For me they are very finicky about returning. However, they do reseed for me and I always have babies around. Some years I seem to have all babies and no blooms. Then the next year a lot of blooming Columbine. I have grown them from purchased seed. I used the winter sowing method. I did NOT have blooms the first year.
I watched a few videos on rooting cuttings of clematis. It looked so easy! So I tried it. I got one to live out of about 24
I guess that is better than zero! I hope you have better luck than I did. I must have been doing something wrong.
