All OO22 fruit seeds listed here are open pollinated. Pepper flowers are mostly self-pollinating, so you can save seeds from the fruit you grow and get the same type of pepper next year with relative reliability. You can't do this with hybrid pepper varieties.
I maybe started some of these plants from seeds, but most of them were from open pollinated, organic varieties I picked up as 50% off desperate seedlings from Oryana. I tried not to start or buy anything too spicy, but you will certainly find a strong kick in this seed pack. Expect a variety of pepper colors when ripe. (Picture not accurate). ~20 seeds per pack.
