Native Apple Trees with Paul Kron

42 min • 22 december 2020

Most apple trees that we grow in our gardens and orchards are not native to North America. DNA tells us that these trees originate in the mountains of Kazakhstan in Central Asia. But there are some crabapple trees that are native to North America. In this episode we talk to Paul Kron, Research Associate at the Plant Population and Evolution Research Lab at the University of Guelph about native apple trees.

Click here to watch a 9-minute video segment from the hour-long podcast to learn the history of apple trees, how feral apple trees differ from native ones, and to learn the mystery around Malus coronaria's reproduction.

MORE INFORMATION:

  • Most of the Husband lab research on Malus coronaria has taken place at rare Charitable Research Reserve in Cambridge, Ontario (https://raresites.org/). Rare is an excellent spot to see Malus coronaria trees in a publicly accessible area.
  • Paul's lab offers apple identification services to homeowners who want to identify the variety of an old apple tree near them.
