List prepared by Michael Pilarski, Friends of the Trees Society

Version 1, March 28, 2015

This list is composed of 150 trees and shrubs which may (or may not) be economically profitable to grow for products/functions or to sell as nursery plants in the Maritime PNW region.  This is admittedly a very preliminary list.

The chief reference for this list, besides the author’s knowledge, is the book “The Complete Encyclopedia of Trees and Shrubs”. 2003, Thunder Bay Press, San Diego California.  816 pages.

I went through the book genus by genus.  This list focuses on zone 6 and zone 7 species (occasionally zone 8) which can be grown in the Maritime Northwest.  This is a preliminary list only and only includes a few of the many notable natives. Many other tree and shrub species adapted to the maritime PNW are listed in my Inland Pacific Northwest 1000 Crops list which focuses on zone 3 to 5 plants, including some zone 6.  Zone 6 is the overlap zone between the Inland and the Maritime Northwest.  Zone 6 is risky in most of the interior Northwest and zone 8 is risky in most of the maritime northwest.  In the maritime PNW, Zone 8 is possible in the urban heat islands or carefully protected situations.

Once again, the tip of the iceberg. I plan to do expanded editions with common names. Still looking for the person who will make this an interactive database.

The keen horticulturist will see many glaring omissions in this list, but for beginning horticulturists and permaculturists a study of the species on this list will expand their plant palates.

Another useful book to consult along these lines is Trees of Seattle by Arthur Lee Jacobson.
