Comments

Silver cinquefoil is ubiquitous around the Watershed, wherever the habitat is flat and wet, such as seeps and creek and pool sides. Although it is native, Potentilla anserina sometimes is taken for an invasive exotic, occupying disturbed ground beside drainage ditches, stock ponds, artesian wells, etc. A common species of the USA West and along the Canadian border across to Maine, Potentilla anserina follows the Rio Grande drainage down through New Mexico to the border with Texas but not farther down stream. Note that some authorities treat this taxon as Argentina anserina.
