Seeking Plant Donations for Elementary School in South Seattle

Hello, I am a current AmeriCorps member and we have been tasked with remodeling the morning entry garden bed. We are seeking any PNW native plants/perennial pollinators or legumes. I've included the dimensions below, unfortunately the bed in its current state is mostly weeds, a few bushes, and rocky soil. This is a permaculture-centered project and would be welcome to receiving any of the following related donations:
-Garden Tools (for students to use while learning gardening)
-Gravel/Landscaping Stones
-Clean Dirt/Compost/Manure
-Anything you would find helpful to the project
