Hibiscus: Rooting Kopper King Hibiscus, 1 by Gitagal

I have a large Kopper King Hibiscus that is spectacular!

This Spring, one of the new growths from the bottom broke off (I stepped on it...).
I had read that the KK can be rooted from stem cuttings, so I put the broken off section in a bottle of water. It has now been about 3 weeks and there are no signs of any roots forming..The cutting is doing great and there are new leaves growing on the stem underwater--but NO roots or nubbies.

Has anyone rooted the KK from a stem? Any advice is welcome.....

Thanks, Gita
