Pale dock

Family: Polygonaceae · Type: perennial · Native

Pale dock is a California native perennial found in northern Sierra Nevada Mountains (Plumas County) in wet meadow margins at elevations of 1,100 meters. Flowering from May to August, this plant produces small flowers clustered in dense terminal whorls with 15 to 25 flowers per cluster. Growing with stout, deeply ridged stems 80 to 200 centimeters tall and a vertical fusiform taproot, it develops impressive height in wet habitats. Its lance-oblong leaves stretch 20 to 55 centimeters long, with flat to slightly wavy margins and acute tips that taper at the base. The fruit is red-brown, approximately 3 to 4.5 millimeters long with three small, nearly equal tubercles.
