Any results would probably be sterile, but I am consdering trying some intergeneric crosses between hibiscus and some related plants in the area. I know this would be more likely to "work" if the choromosome numbers of the plants were the same.
Plants that I am considering:
2. Rose of Sharon (Hibiscus syriacus)
3. Marsh Mallow
4. Roselle (Hibiscus sabdariffa)
5. Some weedy relatives: Flower of an Hour (Hibiscus trionum) and Cheeses (Malva neglecta).
Has anyone had experience with any of these "experiments?
Thanks for your input.
