Reseda, also known as the mignonette, is a genus of fragrant herbaceous plants native to Europe, southwest Asia and North Africa, from the Canary Islands and Iberia east to northwest India. The genus includes herbaceous annual, biennial and perennial species 40–130 cm tall. The leaves form a basal rosette at ground level, and then spirally arranged up the stem; they can be entire, toothed or pinnate, and range from 1–15 cm long. The flowers are produced in a slender spike, each flower small, white, yellow, orange, or green, with four to six petals. The fruit is a small dry capsule containing several seeds.
Silene flos-cuculi, commonly called ragged-robin, is a perennial herbaceous plant in the family Caryophyllaceae. This species is native to Europe and Asia, where it is found along roads and in wet meadows and pastures. In Britain it has declined in numbers because of modern farming techniques and draining of wet-lands and is no longer common. However, it has become naturalized in parts of the northern United States and eastern Canada.
Reseda lutea, the yellow mignonette or wild mignonette, is a species of fragrant herbaceous plant. Its leaves and flowers have been used to make a yellow dye called "weld" since the first millennium BC, although the related plant Reseda luteola was more widely used for that purpose.

Reseda odorata is a species of flowering plant in the reseda family known by many common names, including garden mignonette and common mignonette. It is probably native to the Mediterranean Basin, but it can sometimes be found growing in the wild as an introduced species in many parts of the world. These introductions are often garden escapees; the plant has long been kept as an ornamental plant for its fragrant flowers, the essential oil of which has been used in perfumes. This is an annual herb, producing branching erect stems to 80 centimeters in maximum height. The inflorescence is a spike-like raceme of many flowers. The fragrant flower has six white to yellowish or greenish petals, the upper ones each divided into three narrow, finger-like lobes. At the center of the flower are up to about 25 stamens tipped with large dangling orange anthers.
Sisymbrium loeselii is a species of flowering plant in the family Brassicaceae known by several common names, including small tumbleweed mustard, false London-rocket, throughe(ver:kashmiri) and tall hedge mustard. It is native to Eurasia, and it is known on other continents as an introduced species and in some areas a common roadside weed. It is an annual herb producing a hairy, erect stem which can exceed a meter in height. The leaf blades are divided into triangular, lance-shaped, and toothed linear lobes, and are borne on petioles. The top of the stem is occupied by a raceme of flowers with bright yellow petals each measuring just under a centimeter long. The fruit is a silique up to 3.5 centimeters in length containing tiny seeds.
Sisymbrium orientale is a species of flowering plant in the family Brassicaceae known by the common names Indian hedgemustard and eastern rocket.

It is an annual herb producing a decumbent to erect, spreading, branching stem 10 to 50 centimeters in length. It is coated in short and long rough hairs. The basal leaves are up to 10 to 15 centimeters long and are divided into elongated lobes along the edges; leaves higher on the stem are shorter and sometimes less divided.
