This is a native American heirloom developed by a gardener named Erris Wenk in New Mexico. It may have some Chipotle or Jalapeno as well as Anaheims, Fresnos, Banana/Wax peppers, and Pimento sweet peppers, in its ancestry. And it is definitely not a variety of Serrano.
Wenk’s Yellow Hot is an heirloom variety of Capsicum annuum that was developed by a gardener named Wenk in New Mexico. It is related to Fresno, Siling Lara, Wailua Pepper, Hawaiian Sweet Hot, Chervena Chujski, Achar, Achari, Almapaprika, Banana Wax, and Pimento. As with these other varieties of sweet peppers, this pepper is only sweet when fully ripened until red in color.
This was developed by crossing various Capsicum annuums until an ideal blend of flavor, productivity, disease and insect resistance, and drought tolerance were finally found.
Then, the variety was stabilized… various backcrosses done, until all these desirable characteristics remained relatively stable in the offspring grown from saved seeds.
The varieties used to develop this pepper include New mexico pepper plants in the Anaheim group, and Sweet pepper plants such as Pimento and Chervena Chujski. May also have included Chipotle/Jalapeno plants.
