I’m in love with your plans and goals! Something that’s resisted a lot of wear from our dog’s circuits has been wild violets, and we’re seeing more clovers volunteering in those patches alongside them.
It sounds like just the right amount of ambition to me, I’m hopeful you’ll see great results and will share them with us here!
We’ve had good experiences transplanting them during the early part of the growing season, maybe someone nearby would let you take a clump or three to get you started. They can spread pretty prolifically from a start like that. I haven’t noticed them spreading seed very far, but their roots will spread them out readily.
