Delaware County has no rule against native-plant or meadow landscaping. Native gardens are encouraged for stormwater and pollinator benefits, but you must still meet your municipality's weed and grass-height ordinance, which can flag an unmaintained lot as overgrown.
Neither Pennsylvania nor Delaware County prohibits replacing lawn with native plants, meadows or pollinator gardens, and county conservation and watershed programs promote them. The catch is municipal: local property-maintenance codes still bar noxious weeds and, in many towns, grass or plant growth over a set height (for example, Lower Chichester's twelve inches). A cultivated native meadow is generally treated as an intentional garden and exempt, but an untended lot can be cited as overgrown. To avoid disputes, keep planting beds defined, maintain edges and setbacks, and remove listed noxious weeds. Some Delco municipalities have adopted managed-meadow or 'no-mow' allowances — check locally.
There is no penalty for native landscaping itself. Enforcement only occurs if a property violates the local weed-and-grass ordinance; then standard notice, abatement and lien procedures apply through municipal code enforcement.
