Native plants for naturalizing

Naturalizing means planting something that spreads and self-sows until it reads as a stand rather than a planting — the way to fill a meadow, a woodland edge, or a back acre without buying plants by the hundred. These natives establish and take over from there. Match the plant to the site and let it find its own borders; this is the wrong list for a tidy front bed.
