Nathan Jahnke


Ball Horticultural Co.

Job Title

Culture Research Manager


  • Helped develop a cut flower design course at North Carolina State University with Julie Sherk during graduate school.
  • Earned a Ph.D. in horticultural science: “In many ways, it was a long and hard five years. It is difficult to see the end goal and even more challenging to hope that you find a great and exciting job. Luckily, I did!”
  • In 2022, took on leadership of the technical services team at Ball.


A History of Horticulture: Nathan started Nathan’s Greenhouse with his dad in middle school, the same dad that grew 6- to 7-foot cannas that Nathan and his brothers used for playing ninja. Still today, Nathan could garden and work in the yard all the time.
