Nomenclature and Taxonomy
- Scientific Name: Buglossoides arvensis (L.) I.M. Johnston
- Common Names: Corn Gromwell, Field Gromwell, Bastard Alkanet, Common Gromwell, Ironweed, Sheep Weed, White Ironweed
- Family: Boraginaceae (Borage Family)
- Synonyms: Lithospermum arvense L.
- Note: The plant was formerly known as Lithospermum arvense.
Distribution and Habitat
Corn Gromwell is native to Eurasia and can be found in Europe, North Africa, Siberia, and West Asia, extending to Northwest India. It has also been introduced into the United States and is considered invasive across much of North America, including New England. It typically grows in arable fields and rough ground, often associated with cultivated areas.
Ecological Role
- Corn Gromwell is noted for its presence in areas with rich flora of rare arable plants.
- It has been identified as an invasive species in North America.
- It may suppress the growth of other weeds like sowthistle, doublegee, deadnettle, fumitory, and volunteer lupins.
Morphological Characteristics and Growth Habits
- Growth Form: Annual or biennial herb.
- Height: Typically grows to a height of 10-70 cm, up to 2 feet (approximately 24 inches).
- Stems: Erect or ascending, simple or branched from the base, with one to several stems. Plants are strigose (covered with stiff, bristly hairs).
- Leaves: Alternate, cauline (growing on the stem), sessile (without stalks), lance-shaped, spatulate to elliptic or oblong.
- Roots: Possesses a strong, brown taproot.
- Flowers: White.
Uses and Markets
- Omega-3 Oil Production: Innovative research suggests that Corn Gromwell could be grown commercially in the UK for its omega-3 rich oil. One hectare can produce the same amount of omega-3 oil as 20 tonnes of fish. The oil is an excellent source of stearidonic acid, which converts to omega-3 fatty acids in the body.
- Traditional Uses: An infusion of the leaves has been traditionally used.
Quirky Facts
- Despite its name, Corn Gromwell is not related to corn.
- The name "arvense" comes from the Latin "arvum," meaning "cultivated field," referring to its association with cultivation.
