Hello. My wife and I live in North Gresham at the north-eastern end of the Willamette valley, near the mouth of the Columbia gorge. We have a pretty decent sized back yard that is nicely shaded on the south side by a patch of large, healthy, Douglas fir trees. We want to renovate this space with native plants to give it some color, some life, and hopefully attract friendly and helpful critters like native birds, bees, ladybugs, etc. We're going to be planing under the tree cover in two areas: one to the left(south) of the path (about 12' x 22') and one to the right(north) of the path (about 4' x20'). The goal is to use a variety of shade-loving, native plants, mostly perennials, in groupings/arrangements that once established help take care of each other and require less maintenance than non-native landscaping. Sort of mimicking what you'd find under the trees in a doug-fir forest, but won't overrun the rest of the yard. We've read through native plant guides but don't know what to get or how to place them. So we ask: What are some good plant ideas to use in this landscape? And how should we place them? And/OR do you know of a good resource to use as a guide? Attached for reference is a scale map of the yard (planting areas are shaded) and a photo of the planting areas taken facing west at @4pm, late June. Thank you!
