Darling 58 Update Live Chestnut Chat

September 15, 2023 @ 11:30 am – 1:00 pm
American Chestnut Foundation

The American Chestnut Foundation will hold a Darling 58 Update Live Chestnut Chat on September 15th  from 11:30 am to 1 pm (EDT).

In this chat, TACF’s Chief Conservation Officer Sara Fitzsimmons and SUNY-ESF’s American Chestnut Research and Restoration Project researcher Andy Newhouse, along with others, will share the latest updates about the current status of the Darling 58 transgenic American chestnut.

There has been a lot of excitement around the potential release of this tree, and recent regulatory delays and additional restrictions for distribution may reduce the ability for everyone to get seed, seedlings, or pollen as swiftly as originally hoped. In this Chestnut Chat, we’ll go through some frequently asked questions, including:

  1. When will Darling 58 be deregulated and when can I get a tree? 
  1. How “pure” do deployed, disease-resistant American chestnut populations need to be? 
  1. Will pollen only be sent to those with trees proven to be wild-type American chestnuts?
  1. Will Darling 58 trees get the blight and to what degree? 
  2. Will Darling 58 alone restore the American chestnut? Are we done with research? 
  3. What material is distributed via TACF’s wild-type seedling sales and seed sponsor program? 


Due to the number of people registered for this event, we will not have time to answer every question.
