Lepidium pinnatifidum is a species of flowering plant in the mustard family known in English by the common name featherleaf pepperweed.
The plant is native to Europe, Central Asia, and the Middle East.[1]
It is known elsewhere as an introduced species, particularly as an invasive species in California.
Lepidium pinnatifidum is an annual or perennial herb growing a single erect stem up to 0.5m (01.6feet) tall. The inflorescence is a raceme of tiny flowers made up mostly of millimeter-long sepals. There are usually no petals, but there occasionally appears a vestigial white petal. The fruit is a rounded, notched capsule only about 2mm long.
