hedge mustard

Hedge mustard refers to plants in the genus Sisymbrium, belonging to the mustard family (Brassicaceae). These plants are often weedy and are commonly found in waste areas and fields across the Northern Hemisphere.1

Key characteristics of hedge mustard plants include:
* Flowers: Typically white or yellow with four petals.1
* Seedpods: Long, thin seedpods called siliques.1
* Leaves: Usually coarse and deeply cut.1

One notable species is S. officinale, a Eurasian annual that has naturalized in North America. It was historically used in medicine as a diuretic and expectorant. Other species, like tumble mustard (S. altissimum), can form tumbleweeds, and London rocket (S. irio) is considered an invasive species in some regions.21
