Lepidium campestre is an annual plant
in the Brassicaceae
or mustard
family, native to Europe
, but commonly found in North America
as an invasive
weed. The most notable characteristic of field pepperweed is the raceme
of flowers which forks off of the stem. These racemes are made up of first small white flowers and later green, flat and oval seedpods each about 6 mm long and 4 mm wide. Each seedpod contains two brown, 2.5 mm long seeds.
The stem of field pepperweed comes out of a basal rosette of toothed leaves. The stem is covered in leaves, which are sessile
, alternate and arrow-shaped. The entire plant is generally between 20 and 60 cm tall and covered in small hairs.
The plant is edible. The young leaves can be eaten as greens, added raw to salad
s or boiled for ten minutes. The young fruits and seeds can be used as a spice, with a taste between black pepper
and mustard. The leaves contain protein
