Where to start in Multnomah County
If you have only one spot to fill, sun all day is where Multnomah County gives you the most rated choice (287 plants), and Alkali buttercup (Ranunculus cymbalaria) is the easiest start on that list. Under trees is the hard one here: 105 rated plants, so for that spot it is worth asking a local native-plant society about the 534 unrated natives too.
