Just recently I was successful in producing the following hybrid seed from my gigunda regia:
regia x admirabilis
regia x binata dichotoma giant
regia x binata multifida extrema
regia x capensis giant wide leaf form
Is there potential for these seed being fertile? They were very plump and had the appearance of very healthy normal seed. I haven't been able to find any photos or information on other regia crosses. Have any others been done?
