The first plant is one of the Grape Ferns, possibly Botrychium biternatum (Sparse-lobe Grape Fern).

I, too, am a planted native of Western WA. Throughout my childhood and youth, I foraged for berries all over Western WA. Now, in my own garden, although the majority of my plants are non-native, I have a lot of native plants interspersed here and there, that have volunteered and that I have nurtured, including both red and evergreen huckleberry and oregon grape, trilliums, etc. I have had all the berry plants growing in everything from complete shade to lots of sun. From my berry picking days, to my own plants, I can tell you that, even though they will grow in the shaded understory of the forest, the plants that produce the most berries, by far, are the ones that get more sun, and the more the better. This holds true for the flowering currents. As a berry picker, you always try to find a good thicket at the edge of the woods, with an eastern exposure. They really like several hours of morning sun. Sun exposure between 2 and 4 pm can kill young plants, but once established they can take that as well, if watered properly. I have a volunteer evergreen huckleberry growing out of a log in my back yard, in full sun, that is happy as can be. It gets enough water, because it's near a hardy fuchsia. A caution on fireweed (if that is what it really is). I have lived in Alaska, also, where it could almost be the state flower. It is a root runner and can be quite invasive, especially here in WA, where it doesn't get the winter cold to keep it in check. Salal, also a native, is also a root runner, but it is very hard to get established, if not growing there naturally. I have known people, whose yards are backed by a large forested area, that absolutely hate it. Regarding soil....all our native plants do like a highly organic, slightly acid soil. I have extremely light, sandy soil, which dries out very fast in the summer. My success with the natives has come from giving them a good, deep mulch of medium shredded bark, with fines in it. In the years I don't mulch I can really tell they are not happy. Good luck!

I love wildflowers. I am still discovering blooms I have never seen before here at my place after nearly twenty years. I don't know any of the names but am always pleasantly surprised.

Hello Oboedire, is the second one Solanium laciniatum; Kangaroo Apple, you might need to Google it to see the variations as the pic doesn't show the petiole junction at the fruit. Again try Google for this one; sandpaper fig. I know that the fruit grow along the branches.
