ElPolloDiablo, I find that they root better when they are actively growing. I just recut and stick directly into a pot with
soil, place in cool area close to the house shade. You want to keep the soil damp but not wet. So far I have harvested the white with red center seeds with a tint of pink. I have seedpods on red and pink. Let me know if you are interested. I have a couple of pots with cuttings but they won't be ready until spring.
Some Perennial Hibiscus produce seedpods, some do not.
