There is a very good chance that they will. I have a few peppers that I'm going to be trying to crossbreed that I have kept very separate from everything else. Otherwise, the only way that you would ever know would be planting the seeds and letting them grow through next season. When cross pollination happens, it's never in the actual peppers that grow on that plant. It is the seeds inside that contain the cross of the genetics.

Do you mean that it is the same plant that has been alive for 7 years? If so, that is probably what is happening because it has reached the end of its life cycle. If it's a case that you have been growing from seeds from the same plant for 7 years, then it could definitely be something otherwise.

@@steelcitygreenthumb ye, 7 years alive and never harvest a fruit from it. always dropping all flowers.....sad

​@@EmilDragonuloh, it has never produced any fruit? That is definitely strange. Especially if it has stayed alive for this long and produces flowers every season.
