Big Jim hatch chili peppers ripen from green to red. They are rarely used as in their ripe form, and are almost exclusively used to produce green chili. The peppers are mild when still green, but become more spicy as they ripen to red. Scoville scale: 500–3,000 SHU.
Pollination occurs by insect, bird, wind, humans, or other natural mechanisms. Because there are no restrictions on the flow of pollen between individuals, open-pollinated plants are more genetically diverse. However, as long as pollen is not shared between different varieties within the same species, then the seed produced will remain true-to-type year after year.
