Sisymbrium loeselii
Also called False London rocket, Tall Hedge Mustard, Loesel's Tumble Mustard, Loesel's Hedge Mustard, London False Rocket, Small Tumble Mustard
Small tumbleweed mustard is an annual or biennial weedy herb of the cabbage family, native to Eurasia and now found as a roadside weed on other continents. It grows quickly from seed and is best treated as a weed rather than a garden ornamental.
Sisymbrium loeselii is a species of flowering plant in the family Brassicaceae known by several common names, including small tumbleweed mustard, false London-rocket, 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.
The leaves are spicy enough to make wasabi but can also be mixed into salads and other dishes.
