spotted ladysthumb

Systems Affected (standardized):

disturbed/waste areas, riparian/aquatic, cropland/pastureland, urban/garden

Regions(s) present (updated by AB):

ALL

Impacts:

Negatively impacts agriculture
Reduced native biodiversity

Source? likely to be reintroduced:

P. persicaria seeds are sold for wildflower gardens. These sales are made through seed catalogues and over the internet and there exists the possibility of further introduction as a minor ornamental species. Due to the risks of both accidental and intentional introduction, either as a seed contaminant, via biotic or abiotic spread or from the importation of seed for ornamental planting, further spread of P. persicaria is likely

Info Blurb:

Can be very competitive with crop plants, particularly in moist areas, and has an ability to spread rapidly once introduced to an area. Stands of emergent plants can impede the flow of water in irrigation ditches, canals, and drainage areas. A seed contaminant and an ornamental.
