Seattle plant and tree expert (without peer, in the opinion of many) Arthur Lee Jacobson visits us today to talk about hard-to-plant areas and your plant samples for identification. Wild Plants of Greater Seattle (2nd Edition) and Trees of Seattle (both self-published) are wonderful books off seeing and identifying growing things in the whole of the city. Trees of Seattle provides comprehensive information about over 1400 trees that grow in our region, along with locations of thriving specimens in local neighborhoods.
