question #2
If you have a seed capsule, the reproduction was sexual.
I bug may have done the deed, but the pollinia are lodged in there pretty good. It was either a large bug or maybe you brushed up against a flower the right way. You can see the pollinia through the translucent tissue of the yellow 'nose' (stamenoid?) of a young flower. It looks like the letter "V". The little tail that hangs down is like a tab for the 'spring loaded' pollen. If pushed or pulled the right way, the pollen pops out as if under pressure!
At about 6 weeks, the seed will start to turn color which you can actually see through the translucent capsule tissue! Not sure how long it takes to open, but I'll let you know.
