(Oops, sorry, missed you’re in Kitsap! I’ll leave this up for others, though!)
I’ve done a fair bit of native plant gardening in the PNW, too! If you’re in the Puget Sound, I’d suggest these places to source plants:
-The Kruckeberg Garden - they have plant sales in early and late spring with lots of native species available
-Oxbow Nursery - they have a farm stand in Carnation that has a lot of native plants, as well as some veggies. Stop by Carnation Farms’ farm stand in the evening when you’re there, and you might get a nice elk observation for inat, too!
-Central Puget Sound WA Native Plant Society plant sale in Bellevue - they usually have a lot of experts there who can give good advice
Actually, in general, the WNPS has a lot of plant sales (usually each chapter has one) plus a native plant nursery/seed list on their website. I’d highly recommend checking them out.
Personally, I’ve had good luck with the following in sunny areas of about the same size as the one you’re describing:
-Cascade Penstemon
-Broadleaf lupine
-Great Camas and Common Camas
-Western Columbine
-Bluebell-of-Scotland
-Sea thrift
-Nodding onion
-Oregon stonecrop
-farewell-to-spring
-Solidago elongata
-Red-flowering currant (this does get large, and I prune mine regularly)
I grow a colorful cultivated “Paprika” yarrow, too, although you can also find the white native yarrow for sale some places. They’re the same species, but getting the local native is probably better. I grow toughleaf iris and Douglas’ iris despite the fact that they’re not native this far north in WA, just because I like them lol.
I’ve grown a few other species I would not recommend for your area, despite them being very popular with pollinators. I would not recommend Pacific aster because it tends to spread vigorously. If you have room for it (8’x8’ would be enough for one of them lol), it’s a favorite for all kinds of bees, wasps, and the seeds are a favorite for birds… but it’s just such a bully! I’ve also grown elegant madia, but while it is beautiful, the flowers close up in the morning and it’s rather large - which can cause it to look weedy, especially in late summer. It would be better in a larger space, in my opinion. I’ve grown shooting stars and checker lily from Kruckeberg, too, but have found them to be rather tender. The shooting star in particular requires a LOT of water.
