The Ohio Department of Agriculture (ODA) in the US banned 38 plants for sale or distribution in the state based on their invasive characteristics. The ban is effective as of the beginning of this year. ODA defines invasive plants as plant species that are not native to Ohio whose introduction causes or is likely to cause economic or environmental harm, or harm to human health as determined by scientific studies. The new rules are established after nearly two years of stakeholder outreach.
“In some cases businesses may have invested considerable time and resources into growing some of these plants. These rules include a grace period for the prohibition to take effect for some species, which allows businesses time to transition toward alternative plants to market as replacements”, explains ODA.
The list includes Ailanthus altissima, Alliaria petiolata, Berberis vulgaris, Butomus umbellatus, Celastrus orbiculatus, Centaurea stoebe ssp. Micranthos, Dipsacus fullonum, Dipsacus laciniatus, Egeria densa, Elaeagnus angustifolia, Elaeagnus umbellata, Epilobium hirsutum; Frangula alnus, Heracleum mantegazzianum, Hesperis matronlis, Hydrilla verticillata, Hydrocharis morsus-ranae, Lonicera japonica, Lonicera maackii, Lonicera morrowii, Lonicera tatarica, Lythrum salicaria, Microstegium vimineum, Myriophyllum aquaticum, Myriophyllum spicatum, Nymphoides peltata, Phragmites australis, Potamogeton crispus, Pueraria montana var. lobate, Ranunculus ficaria, Rhamnus cathartica, Rosa multiflora, Trapa natans, Typha angustifolia, Typha x glauca, and Vincetoxicum nigrum. The ban on Lythrum virgatum is effective January 7, 2019 and on Pyrus calleryana January 7, 2023.
