Plant Guide

Use soil moisture sensors to measure the soil moisture of Polygonum mississippiense Stanford.

Fact Sheet

Uses

This plant is an excellent wildlife food plant, especially for waterfowl. Twenty species of ducks, geese, bobwhites, mourning doves, ring-necked pheasants, and four species of rails, as well as 30 nongame birds, eat the seeds. Dense stands provide cover for young waterfowl, marsh birds, and wintering pheasants. Plants and/or seeds are eaten by white-footed mice, muskrat, raccoons, and fox squirrels.

Status

Please consult the PLANTS Web site and your State Department of Natural Resources for this plant’s current status (e.g. threatened or endangered species, state noxious status, and wetland indicator values).

Description

Knotweed Family (Polygonaceae). Pennsylvania smartweed is an annual herb that has small, five-parted pink or rose colored flowers on a short spike. It grows 2 to 4(6) feet high. The flowering branches have stalked glands. The stems have a reddish color and swollen nodes. The alternate leaves have sheaths extending around the stems. The seeds are black, shiny, flattened, and almost round. There are approximately 62,000 seeds per pound.

Adaptation and Distribution

Distribution

Distribution

Pennsylvania smartweed is adapted to soils of all drainage classes except droughty soils. It commonly occurs on mudflats of fresh water to moderately brackish areas throughout the Northeast. Pennsylvania smartweed is distributed throughout the entire Unites States, excluding a few northwestern states. For a current distribution map, please consult the Plant Profile page for this species on the PLANTS Web site.

Establishment

A seedbed that reduces most weed competition and permits smartweed to be covered by one inch of soil depth is usually sufficient, Drop water quickly and broadcast seed on top of wet ground in mudflats or drawdown areas, Seed after the last killing frost in the spring, Smartweed may be seeded later so that seed maturity coincides with the arrival of migratory birds, Seeds are generally broadcast at a rate of 10-15 pounds per acre, Robert H, Use soil moisture sensors to measure the soil moisture of Polygonum mississippiense Stanford., Mohlbenbrock USDA NRCS 1989 Midwest Wetland Flora @ USDA NRCS PLANTS
