Leominster, MA Landscaping Rules: Native Plants (2026)

Native plant landscaping in Worcester County benefits from MassDEP drought management policies and municipal climate action plans rather than a specific state mandate. The MA Water Management Act (MGL c. 21G) and MassDEP's model water use restrictions encourage drought-tolerant landscaping. MIPAG (Massachusetts Invasive Plant Advisory Group) and 333 CMR 10.00 (administered by Department of Agricultural Resources) maintain a Prohibited Plant List of 69+ invasive species that cannot be sold, propagated, or distributed — including Asiatic bittersweet, Japanese knotweed, purple loosestrife, burning bush, and Norway maple. Property owners are encouraged but generally not required to remove existing invasives, though some wetland mitigation orders require removal. Native alternatives promoted by UMass Extension, Grow Native Massachusetts, and Mass Audubon include little bluestem, serviceberry, red oak, winterberry, black-eyed Susan, goldenrod, and highbush blueberry. The City of Worcester Climate Action Plan promotes native/climate-resilient plantings in municipal projects. Central Mass Regional Stormwater Coalition offers rain garden education. HOA restrictions on lawn replacement are less common in Worcester County than in newer sunbelt developments, and MA has no statute directly preempting HOA turf requirements (unlike FL §720.3075). Worcester County towns in the Quabbin watershed promote native plantings under DCR watershed protection initiatives.
