Hi sagiXsagi. I procured the seeds form somebody in Queensland, Australia. Whether or not that is their origin I'm unsure. Yes, these are autumnalis. I've yet to find out if that cutting took, it looks fine except it's grown no leaves yet. I'll know more once the weather cools.
No seeds as of yet. Something keeps eating the flower. I'll keep you in mind if I ever get seeds.
Thanks for your interest. I really enjoy growing these plants.
