It is too late for this year, but the Rhody can be gotten from the annual Snohomish Conservation District plant sale at the shocking price of three for $8. Now that is cheap. Possibly there is some King County organization selling natives real cheap. Check out the Conservation District website, the plant list is still available to look at, it's the cheapest way to get plants that I know.

We are in the Snohomish Conservation District, and were the happy recipients of a large reveg project - the District provided all the plants and manpower.
