Here is a list of trees for gardens in Seattle, the Pacific Northwest & USDA Zone 8. Many will tolerate colder climates.  They have good form, lovely flowers, colorful fall foliage & other characteristics that endear them to many gardeners. Most of these are deciduous.  Evergreen trees are noted.  Some may be difficult to find. When local nurseries fail, try mail-order nurseries.  Forest Farm is a good source for uncommon trees.  This list is not meant to provide detailed information on trees, but to introduce you to some you may not know, or remind you of those you have forgotten.  Basic characteristics are included to help you sort through the lists.  Be sure you know how widely these trees spread before you plant them, to allow enough space.  Narrow trees are listed separately here.  An abundance of detailed information is available on the web.  Good reference books on shrubs are The Hillier Gardener's Guide to Trees & Shrubs edited by John Kelly, Sunset Western Garden Book

The Arbutus menziesii in Seward Park is truly natural art. I will have to look into it for our own zone 6b but I doubt it. I do love its form.

I love your lists! I will take them to work. I love seeing what other areas of the country can plant. We have a few ginkgo's here, but they are very slow growers here. We could never grow the cypress here. They might have a couple at the botanic gardens because they can fuss over them there. But in a residential yard, never. But I love the info!
