No Lehigh County rule limits native plantings, and Pennsylvania encourages them. The catch is Allentown's 10-inch weed limit: a deliberate, maintained native or meadow garden is fine, but neglected overgrowth can still be cited as weeds.
Lehigh County does not regulate landscaping choices, and Pennsylvania actively promotes native and pollinator plants through DCNR and Penn State Extension programs. Nothing bars a resident from planting native grasses, wildflowers, or a meadow. The practical limit is the municipal weed ordinance: Allentown (§649-2) prohibits weed growth over 10 inches, and enforcement generally targets neglected, unmanaged overgrowth rather than an intentional, tended landscape. To avoid a citation, keep native beds clearly cultivated, edged, and free of noxious weeds like ragweed or poison ivy. Some municipalities have adopted managed-landscape or no-mow exemptions; check your local code before converting a lawn.
A native garden that becomes neglected overgrowth can be cited under the municipal weed ordinance, with fines up to $1,000 and City abatement in Allentown.
