Reseda (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 (4–6 mm diameter), white, yellow, orange, or green, with four to six petals. The fruit is a small dry capsule containing several seeds.
Other common names include weld or dyer's rocket (for R. luteola), and bastard rocket.
