Multiflora Rose (Rosa multiflora), looking mighty pretty right now. But it is an exotic invasive plant that is banned or prohibited in many states. Here in the mountains of central Virginia it is growing in dense thickets in the forest, crowding out native plants.

Native to Japan, Korea, and China, Multiflora Rose was brought to the United States in 1866 to be used as rootstock for ornamental roses. The US Soil Conservation Service in the 1930s suggested its use as a living fence, and for erosion control. In the 1960s scientists were recommending the plants for shelter and a food source for wildlife. And more recently highway median strips have been planted with Multiflora Rose to help eliminate headlight glare from oncoming traffic and to help stop or slow, out of control vehicles.

This plant is a climbing and spreading bush that can grow 1 to 2 feet each month during its growing season, reaching out 10 to 15 feet. Producing 500,000 seeds each year, with a seed viability of 10 to 20 years.

Right now, as the bushes are blooming, there is a native plant to looks quite similar. Blackberry (Rubus fruticosus). The Blackberry blossoms are nearly the same size, with similar white petals (5 petals on each blossom). BUT those Blackberry blossoms have a soft green center with pale green stamens, while the blossom of the Multiflora Rose, has very bright yellow stamens at their center. And keep in mind that Blackberry bushes are not climbing plants.

I hope you don’t find any.
