Hogan Cedar Trees


  • It is a unique form of Thuja plicata, the western red cedar, which grows naturally only in the Gresham area.

  • It has been recognized nationally as an important plant in horticulture.

  • The Oregon Association of Nurserymen's publication, 1999-2000 Directory and Buyer's Guide listed 13 commercial nursery producers of the Hogan Cedar. These are sold nationally. All of these trees trace their origin to a small pocket of trees in Gresham.

  • The original stand is worth preserving, it represents a unique and important gene pool.

  • The population center is located where Hogan Road meets Johnson Creek. These are wind pollinated trees, and the Hogan gene pool extends as a relatively continuous population of trees exhibiting the tall, dense, narrow Hogan form for about one mile from this population center.
