starting heucheras from a single leaf.
It really did work. I took about a dozen leaves and potted each one up about 4-6 weeks ago. Today I knocked a couple of them out of their pots and they had roots. When you take a leaf make sure you pull it away from the main stem. It should have a flare at the end of the leaf where it pulled away. I used Rootone powder and just potted them up. Now that I know it works I'm going to do a lot more. I lost a couple but I figure at least 80% success can't be bad.
