Gabriel from Swansons Nursery near Seattle replied to my email. Thanks Gabriel! Here's what he said I have.
"The plant you have is a type of Ceanothus. There are many types of Ceanothus, but the variety pictured, to me, looks like ‘Italian Skies’. It is rather unusual for Ceanothus to be trained up on a single trunk like the one you have. Usually it is a dense shrub or multi-stemmed small tree.
Please let us know if you have any other questions.
Gabriel"
