Clone my favorite Columbine
You are correct about seeding the columbine - it is likely a hybrid and will not breed true. I have done quite a bit of research on columbine and asexual reproduction such as root cuttings. The only item I cam across was simple division. However, It couldn't hurt to try cuttings. Be sure to use a rooting hormone when you do. And, you may check to see if the breeder of the columbine has a patent or royalty on the specific columbine. It may be illegal to clone, since it is a hybrid.
