Begonia alchemilloides, B. sp 'Caparaó'
Has anyone grown either of these? I started them both to help preserve miniature species, and also hopefully breed them into some neat new miniatures someday.
I've finally gotten just a few seeds of B. alchemilloides to germinate, so hopes are renewed for little miniature tuberous begonias I want to create from it. Once it got past the second true leaf it started growing well. From the picture, if I were naming it, I might have picked "saxifragoides" instead:
B. sp 'CaparaÃ³' is another smallish one. It has fun peltate leaves, which I would like in miniature begonias too. It looks like it may be rhizomatous from this picture:
It was my third and last sowing, the last seeds in the packet of 'CaparaÃ³'. One lonely seed germinated, and it's now working on its third leaf
I'm sure there are more small Begonia species out there too, I'll be looking and listening for species that are in the size range of miniatures especially!
