That’s a very narrow strip and it’s literally an nth away from grass. You might be better off letting the grass fill it in. Many of the other suggestions sound fine, but wont be in the long run.

Some of these might be better fits than others, but here is the general list of native shrubs that I give out to people so you have plenty of options to consider. Some would need more pruning than others, personal favorites would be mock orange, tall oregon grape, California bay laurel, Douglas spirea, osoberry, red flowering currant. If you want something for privacy sooner, consider planting both a shrub and a vine, and install a trellis for the vine to climb a lot faster than a shrub can grow. Pink honeysuckle or orange honeysuckle are native options. -Deciduous shrubs [all are at least full sun to part shade]: red flowering currant (important very early blooms), mock orange, Douglas spirea (great lilac alternative, more aggressive in wetter areas), rose spirea, birch leaf spirea (early blooms), thimbleberry, blackcap raspberry, salmonberry, osoberry (important very early blooms), Nootka rose (can handle mostly shade), snowberry (can handle mostly shade) -Small trees / large shrubs (deciduous): vine maple, ocean spray, serviceberry, red osier dogwood (prefers more moisture), cascara (large shrub to medium tree) -Evergreen shrubs: pacific wax Myrtle, salal, evergreen huckleberry, California bay laurel (gets big or can be hedged), tall Oregon grape, low Oregon grape, ceanothus (tall and short varieties), manzanita, pacific rhododendron (early blooms) More on reddit.com
