The Story of Joe's Round
This pepper is from the Sestito family of Troy, New York. They passed the seeds to Dr. Carolyn Male and, as a long time member of Seed Savers Exchange, Male listed the seeds in the 1996 yearbook.
Pepper species are native to the Americas and have been cultivated for thousands of years. The Spanish and Portuguese brought them back to Europe and to their colonies in Africa and Asia. From there peppers continued to spread and develop.
The chemical in hot peppers that causes a burning sensation is known as capsaicin and can be found in the highest concentration in the white pith around the seeds.
