Another Nasty Invasive: We are
continually battling multiflora rose here at Boxerwood and I’ll bet you are
too, maybe without even knowing it. This
rose was introduced to the eastern United States in 1866 as a rootstock for
ornamental roses. In the 1930’s, the U.S. Soil Conservation Service started
using the rose for erosion control and as ‘living fences’ to control
livestock. More recently, the plant was
used on highway median strips as a crash barrier and to reduce headlight glare
(this is also how we got the notorious and ever-present Autumn Olive). Multiflora rose is an aggressive (and the key
word here is aggressive) large, multi-stemmed shrub with arching stems and
recurved thorns. Small white or pinkish flowers bloom in May and small bright
red rose hips form in late summer through winter. The tips of the canes often reach the ground
and root. Here at Boxerwood, we have had
multiflora rose climb thirty feet into trees.
Birds spread the plentiful seed everywhere.
How to eradicate it? In fields, repeated cutting or mowing at the rate of three to six timesover a period of two years
seems to work. For smaller infestations,
late in the season, cut the plant to the ground and paint the remaining stems
with a systemic glyphosate herbicide such as Roundup.
