Rhamphospermum nigrum (syns. Brassica nigra and Sinapis nigra), black mustard, is an annual plant native to cooler regions of North Africa, temperate regions of Europe, and parts of Asia. It is cultivated for its dark-brown-to-black seeds, which are commonly used as a spice.
It blooms in summer (from May onwards in the UK). The flowers have four yellow petals, which are twice as long as the sepals. Each stem has around four flowers at the top, forming a ring around the stem. Later, the plant forms long, beaked seed pods, which contain rounded seeds.
R. nigrum also resembles Hirschfeldia incana (hoary mustard, formerly known as Brassica geniculata), a perennial plant.
The Latin-specific epithet nigrum is derived from the Latin word for black.Allen J. Coombes D. Gledhill This is due to the black seeds.
In North Africa, it is found within Algeria, Egypt, Eritrea, Libya, Ethiopia, Morocco and Tunisia. Within Asia, it is found in Afghanistan, Armenia, the Caucasus, China (in the provinces of Gansu, Jiangsu, Qinghai, Xinjiang and Xizang), Cyprus, India, Iran, Iraq, Israel–Palestine, Kazakhstan, Lebanon, Syria and Turkey.
In eastern Europe, it is found in Belarus, Moldova and Ukraine. In middle Europe, it is found in Austria, Belgium, Czech Republic, Germany, Hungary, Netherlands, Poland, Slovakia and Switzerland. In northern Europe, in Ireland and the United Kingdom. In southeastern Europe, within Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Greece, Italy, Montenegro, North Macedonia, Romania, Serbia and Slovenia. In southwestern Europe, it is found in France and Spain.
It was introduced to the Pacific coast of North America and is considered an invasive species. The plant was brought here centuries ago by Catholic missionaries during the era of Spanish exploration and colonization, as a food crop, according to Matt Loftis, a manager of Mountain Forestry Department at TreePeople in Los Angeles, California. It has since thrived unchecked, aided by a similar Mediterranean climate in Southern California.
A spice is generally made from ground seeds of the plant,
The young leaves, buds and flowers are edible. In Ethiopia, where the plant is cultivated as a vegetable in Gondar, Harar and Shewa, the shoots and leaves are consumed cooked and the seeds used as a spice. Its Amharic language name is senafitch.
Since the 1950s, black mustard has become less popular as compared to Brassica juncea, because some cultivars of brown mustard have seeds that can be mechanically harvested in a more efficient manner.
