I fear this is going to reveal just how dense I am, but ...

1 Do sweet and hot peppers cross-pollinate?

2 Can only two plants cross, or can it be more than two?

3 Is there a way to deliberately (paintbrush in stamens?) cross pollinate?

I'm just curious. I find the whole plant breeding thing kind of fascinating. There are some things I love and I think it would be so interesting to try deliberately CPing them, growing out a bunch of seeds the next year to see if there were any good results, saving those and planting again, etc.
