PERENNIAL PEPPERWEED-Lepidium latifolium
Brassicaceae-(Mustard family)
This plant is a perennial, 1 to over 3 feet in height; leaves lanceolate, bright green to gray-green, entire to toothed, basal leaves larger than upper leaves; inflorescence a raceme. Flowers are white, in dense clusters near ends of branches, very small; fruit a silicle; seeds 2 per fruit, rounded, flattened slightly hairy, about 1/16 inch long, and reddish-brown.
Perennial pepperweed is a native of southern Europe and western Asia but is now found in many parts of the United States. It has been declared noxious in a number of western states. Deep-seated rootstocks make this weed difficult to control. Perennial pepperweed gows in waste places, wet areas, ditches, roadsides, and cropland. Flowering occurs from early summer to fall.
Non-standard name: broad-leaved peppergrass, tall whitetop, Virginia pepperweed.
