Multiflora rose is a medium-sized, thorny shrub with a spreading growth form, often forming thickets. Does this plant displace native plants and dominate (overtop or smother) the plant community in areas where it has established? After establishment, individuals are capable of increasing their size by 1–2 feet a week during midsummer. These uses encouraged its distribution, usually via root cuttings, to landowners through State Conservation departments.
