I was just messing around pulling dead leaves and of course I pulled off a good one. Then it hit me stick it down to see if it will root. One had all the end of the stem the other looks like only part of it come off. The weird thing is the mother got morning sun but the leaf was under cover of mother leaves.
Going to try this on my old favorite Purple Place (have made many divisions). Some of them are different shades.
I tried willow water with the stems years ago but they didn't root.
Julia, try it and let me know if it works.
