- Comments
- The first North American records of this Eurasian grass were documented in Maryland in 1997 and 2000. Since then, it has become a rampant forest weed at a number of Maryland sites. The size of some populations discovered in Virginia since 2005 indicates that the species has been locally established but undetected for some time. Its sticky-glandular spikelets and its perennial stoloniferous habit favor quick dispersal and local spread once established at a site. Despite a multi-agency effort at early detection and eradication, populations in new areas are being discovered with increasing frequency. The species is spreading southward rapidly and can be expected to become a widespread invasive in forest habitats. The current map certainly does not represent the full distribution of this taxon in the state; voucher specimens from all populations are needed.
- Habitat
- Mesic upland forests (both disturbed and undisturbed), well-drained stream bottoms, and shaded clearings. First discovered in Virginia in 2005, it is now known from many counties in the northern two-thirds of the state and a few in the southern counties.
