It is an easy matter to save and germinate the seeds. Typically pepper plants are self pollinating.
BUT, as everything from the sweet Yolo Wonder to the hottest of the hot are the same species, crosses do occur.
You may discover your second generation plants to be a cross of 1/2 sweet bell pepper X 1/2 Jalepeno.
We get some amazing crosses in the garden of tomato hybrids, or squash plants, or cantaloupe crosses when a volunteer seedling is allowed to bear fruit.
Your heirloom seed is no longer heirloom when a friendly honey bee deposits a bit of stray pollen on the flower.
