I have sprouts in both begonia containers. It has been 9 days since they were seeded. They're barely visible specks, but I definitely see green.
I really didn't expect the B. boliviensis to germinate. I saved those seeds from my barely alive plants last year. None of the pods completely ripened on the plant. They fell to the ground while still pink and full of moisture. I saved a few anyway, and now they've sprouted. Very cool!
