Morris County does not require native plants, but New Jersey encourages them. NJDEP model tree and stormwater ordinances favor native, non-invasive species for replacement trees and green infrastructure, and towns may adopt native-plant lists.
There is no countywide native-plant mandate for private landscaping in Morris County. New Jersey promotes native species through several channels: NJDEP's stormwater and green-infrastructure guidance recommends native, non-invasive plants; the state's model tree removal-replacement ordinance directs municipalities to publish an approved replacement-tree list (favoring natives) and a list of species that cannot be used. Some Morris County towns and the Morris County Park Commission use native-plant standards in public projects and stormwater basins. For your own yard, native plantings are strongly encouraged for pollinators and stormwater but are voluntary unless your municipality's landscaping or site-plan ordinance requires them for new development.
No county penalty for plant choice on private lots. New development may have to meet a municipal landscaping/site-plan ordinance that specifies native or non-invasive species.
