Hi there, I am looking to plant a tree in our inner NE Portland, OR backyard. We have an approx 2200 sf lot, about 2/3 of which is open back yard, and with no major plantings. Despite being an ardent supporter of native species, I have begun to prioritize drought tolerance and pollinator friendly options, but am concerned about planting problematic or invasive species. I was considering planting a albizia julibrissin ‘summer chocolate' because its pollinator friendly, drought tolerant and grows quickly but have read it can be invasive in some areas. Is it considered invasive in the Portland area?
I've also considered planting Jeffrey Pine or Willamette Pondersa, as well as a couple different oaks (Quercus agrifolia or myrsinifolia).
Thanks in advance!
