The bigger picture

I'm holding a handful of jewelweed seeds and some tree seed from down on River Street (about a mile up the road from the knotweed site), with the intention of spreading them at the knotweed site in the next week or two. I'm thinking of mulching right on top of the landscape fabric and putting down things like:

Ferns
Plantain
Jewelweed
Dandelion
Dogwood
Aster

Any plants that grow strong early in the spring would be terrific; please e-mail me your suggestions or post here as a comment!
