Lepidium campestre | |
Lepidium campestre, the field pepperwort, [1] field peppercress, field peppergrass, field pepperweed or field cress, is usually a biennial with some form of 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. [2] 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. [2] The entire plant is generally between 20 and 60 cm tall and covered in small hairs. [2]
Field pepperweed grows in disturbed land, crops, and waste places. [2] It can tolerate most soils.
The plant is edible. The young leaves can be eaten as greens, added raw to salads or boiled for ten minutes. [3] The young fruits and seeds can be used as a spice, with a taste between black pepper and mustard. The leaves contain protein, vitamin A and vitamin C. [3]
Field cress has been targeted for domestication at the Swedish University of Agricultural Sciences (SLU), because it holds high agronomic promise as a biennial/perennial oilseed crop as it has many good characteristics of a high-yielding winter-hardy crop. [4] [5] Unlike any other oilseed crop, field cress can be highly productive in the northern parts of temperate regions and has been successfully grown in Umeå, Sweden (40 km south of the Arctic circle) where it can yield correspondingly 3.3 tons/ha. In addition, field cress provides important ecosystem services as it functions as a cover crop during winter and can be undersown a spring cereal. [6] The oil of field cress is suitable for different industrial applications such as production of hydrotreated vegetable oil diesel (HVO). The researchers at SLU have identified and mapped several genes in field cress that are known to be important for domestication related traits such as flowering time, pod shattering and seed dormancy.

Brassicaceae or Cruciferae is a medium-sized and economically important family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family. Most are herbaceous plants, while some are shrubs. The leaves are simple, lack stipules, and appear alternately on stems or in rosettes. The inflorescences are terminal and lack bracts. The flowers have four free sepals, four free alternating petals, two shorter free stamens and four longer free stamens. The fruit has seeds in rows, divided by a thin wall.
The turnip or white turnip is a root vegetable commonly grown in temperate climates worldwide for its white, fleshy taproot. Small, tender varieties are grown for human consumption, while larger varieties are grown as feed for livestock. The name turnip – used in many regions – may also include rutabaga, neep or swede.
Cress, sometimes referred to as garden cress to distinguish it from similar plants also referred to as cress, is a rather fast-growing, edible herb.
Leaf vegetables, also called leafy greens, pot herbs, vegetable greens, or simply greens, are plant leaves eaten as a vegetable, sometimes accompanied by tender petioles and shoots. Leaf vegetables eaten raw in a salad can be called salad greens.
Brassica rapa is a plant species growing in various widely cultivated forms including the turnip ; Komatsuna, napa cabbage, bomdong, bok choy, and rapini.
The mustard plant is any one of several plant species in the genera Brassica, Rhamphospermum and Sinapis in the family Brassicaceae. Mustard seed is used as a spice. Grinding and mixing the seeds with water, vinegar, or other liquids creates the yellow condiment known as prepared mustard. The seeds can also be pressed to make mustard oil, and the edible leaves can be eaten as mustard greens. Many vegetables are cultivated varieties of mustard plants; domestication may have begun 6,000 years ago.
Lepidium latifolium, known by several common names including perennial pepperweed, broadleaved pepperweed, pepperwort, or peppergrass, dittander, dittany, and tall whitetop, is a perennial plant that is a member of the mustard and cabbage family.
Lepidium is a genus of plants in the mustard/cabbage family, Brassicaceae. The genus is widely distributed in the Americas, Africa, Asia, Europe, and Australia. It includes familiar species such as garden cress, maca, and dittander. General common names include peppercress, peppergrass, pepperweed, and pepperwort. Some species form tumbleweeds. The genus name Lepidium is a Greek word meaning 'small scale', which is thought to be derived from a folk medicine usage of the plant to treat leprosy, which cause small scales on the skin. Another meaning is related to the small scale-like fruit.
Lepidium virginicum, also known as least pepperwort or Virginia pepperweed, is an herbaceous plant in the mustard family (Brassicaceae). It is native to much of North America, including most of the United States and Mexico and southern regions of Canada, as well as most of Central America. It can be found elsewhere as an introduced species.
Cardamine hirsuta, commonly called hairy bittercress, is an annual or biennial species of plant in the family Brassicaceae, and is edible as a salad green. It is common in moist areas around the world.
Thlaspi arvense, known by the common name field pennycress, is a flowering plant in the cabbage family Brassicaceae. It is native to Eurasia, and is a common weed throughout much of North America and its home.
Lepidium densiflorum is a species of flowering plant in the mustard family known by the common names common pepperweed, prairie peppergrass, elongate peppergrass, hairy-fruited peppergrass, and large-fruited peppergrass.
Lepidium perfoliatum is a species of flowering plant in the mustard family known by the common names clasping pepperweed and perfoliate pepperwort. It is native to Europe and Asia and it can be found in other parts of the world as an introduced species.
Lepidium didymum, the lesser swine-cress, is a species of flowering plant in the family Brassicaceae.
Lepidium dictyotum is a species of flowering plant in the mustard family known by the common names alkali pepperweed and alkali pepperwort.
Lepidium barnebyanum is a rare species of flowering plant in the family Brassicaceae known by the common names Barneby's pepperweed, Barneby's pepper-grass, and Barneby's ridge-cress. It is endemic to Utah, where there is a single population in Duchesne County. It is a federally listed endangered species of the United States.
Lepidium papilliferum is a rare species of flowering plant in the mustard family known by the common names Idaho pepperweed and slickspot peppergrass. It is endemic to Idaho in the United States, where it is mostly limited to a specific habitat type in the southwestern part of the state. It was federally listed as a threatened species in 2009.
Lepidium heterophyllum,, is a species of flowering plant in the mustard family which is native to parts of western Europe, growing in shingle banks, wasteland or cultivated fields.
Lepidium coronopus,, is a species of flowering plant in the mustard family which is native to parts of Africa, western Asia and Europe, growing in shingle banks, wasteland or cultivated fields.
