## Description

Lepidium latifolium normally grows to 30–100 cm (12–39 in), but may grow as tall as 2 m (6.6 ft). It has numerous woody stems, alternating waxy leaves and clusters of small white flowers. It produces small (1.6 millimeter) fruits which each contain two reddish seeds. It has an extensive root network, known to reach 9 ft (2.7 m) in depth, and constituting 40% of the total biomass of the plant.[3]

## Distribution

This plant is native to southern Europe, Mediterranean countries and Asia as far east as the Himalayas. It is an introduced species in North America, where it grows throughout the United States and Mexico, and Australia . It may have been introduced to the United States when its seed got into a shipment of sugar beet seeds.[3]

## Invasive plant

The plant is most invasive in wetland habitats, including riparian zones; from there it easily spreads to other ecosystems, such as sagebrush.[3] It is perceived as a threat to salt marshes in southern New Hampshire, United States , prompting the Department of Environmental Services and the U.S. Fish and Wildlife Service to look for it in the Hampton-Seabrook Estuary in 2008, where it is thought to have spread. The agencies were recruiting volunteers to help look for and properly remove it from this area.[4] It is also a pest in the Monte Vista and Alamosa National Wildlife Refuges in Colorado and Malheur National Wildlife Refuge in Oregon, and many other sites.[3]

## Uses

### Edible uses

The leaves, shoots, and fruits of this plant are all edible. In Ladakh in the Himalayas, the spring leaves are prized as a vegetable. The peppery edge or bitterness is removed by first boiling the young shoots and leaves, and then soaking in water for two days. Cooked like spinach, it makes a nutritious vegetable.[5]

### Other uses

Dried stems of Lepidium latifolium are sometimes used in flower arrangements.
