In Ohio, certain related species of Lythrum salicaria are allowed to be sold; whereas some states ban the entire genus. Contact the Ohio Department of Agriculture for details. All laws and regulations concerning noxious weeds are subject to change.

Multiflora Rose Rose multiflora

Multiflora rose may be used by licensed nurseries as rootstocks for other rose species. To use this plant for any other reason, a special permit is needed from the Ohio Department of Agriculture. Multiflora rose is a thorny and invasive woody plant. It is difficult to eliminate once established. Note: multiflora rose can be distinguished from other roses by the presence of fringe-like stipules at the leaf bases.

Ohio Noxious Seed Law

Ohio also has a noxious seed law, enforced by the Ohio Department of Agriculture. It prohibits certain weed seeds from being present in crop seed. Most of the prohibited species are troublesome perennials that spread quickly and weeds that have not yet been introduced to Ohio. For a list of weeds prohibited in commercial seeds, contact the Ohio Department of Agricultures Division of Plant Industry. Lists are available of weed seeds which are prohibited in crop seed (primary noxious weeds), and weed seeds which are not allowed to exceed 0.25% of a crop seeds weight (secondary noxious weeds). No crop seed may contain weed seed of any kind exceeding 2.5% by weight.
