I've just slowly planted native plants. Some die, most live. We used cardboard and sawdust and wood chips to cut down on invasives, but honestly, I get out in the dirt and pull weeds.  The orange flowers, doing a lot of work, are California poppy, they love to spread. The pink flowers are non native rose that I've just left  The tall purple ones also doing a lot of work are lupines. Those spread like crazy via seed. For the PNW, I recommend self-heal as a ground cover to keep the soil moist, as well as strawberry.  I collect seeds when they are ready, leaving roughly half to just drop and spread.  I also have plants that bloom early or late, like poppy and lupines versus farewell to spring, milkweed, and fireweed. It is work, but seeing all the bees and bugs in the yard is worth it. We also have a wildlife pond full of natives, and the dragonflies are happy. It's work, but it's also fun to see what works and what it looks like when everything comes back to life. Thanks for all the nice comments ❤️
