Edible Parts: Leaves  Seed  Seedpod
Edible Uses:

Miner's pepperweed is one of the most useful edible species within the Lepidium genus. Its relatively mild leaves, edible seedpods, and flavourful seeds provide several food uses throughout the growing season. Although not a major staple, it is a dependable wild herb and seasoning that rewards foragers with an abundant supply of spicy greens and pepper-like seeds across much of North America [2-3]. The young leaves, immature seedpods, and seeds are edible [2-3]. Fresh leaves have a pleasantly spicy flavor typical of the mustard family, without the excessive bitterness found in some of the hotter desert pepperweeds. They can be eaten raw in salads or cooked as a potherb. The flavor is strongest in mature plants and milder in young spring growth [2-3]. You can eat tender seedpods before they dry, while mature seeds can be used whole or ground as a pepper substitute. Like other Lepidium species, the seeds add a pleasant mustard-like spice to a wide variety of foods [2-3]. Edibility Rating: 4 out of 5 – One of the better edible pepperweeds, producing useful leaves, seedpods, and seeds with a pleasant spicy flavor. Taste and Preparation: Fresh leaves have a crisp texture with a spicy, peppery taste resembling mustard greens or cress. Compared with many other Southwestern pepperweeds, they are relatively mild and lack strong alkaline or unpleasant bitter flavors. Boiling softens both the texture and pungency, producing an excellent cooked green. You can also save the cooking water for soups, where the peppery flavor becomes pleasantly subdued. The seeds are highly aromatic and can be ground fresh as a seasoning. Their flavor more closely resembles ground mustard seed than black pepper. A small quantity is enough to flavor eggs, potatoes, beans, soups, stews, poultry, or meat dishes. Cooking reduces much of the pungency, making the seeds suitable for incorporation into porridges or other cooked foods [2-3]. Seasonality (Phenology): Miner's pepperweed blooms from April to July. Harvest young leaves in spring, before flowering. Immature seedpods develop soon after flowering, while mature seeds become available from late spring through summer. Nutritional Value: The leaves provide vitamins, minerals, antioxidants, and dietary fiber typical of leafy mustard greens. The seeds contain oils, protein, and glucosinolates responsible for their characteristic peppery flavor. Traditional Uses: Although relatively few traditional food records exist specifically for miner's pepperweed, its edible characteristics closely resemble those of poorman's pepperweed (Lepidium virginicum). Like many pepperweeds, people valued the seeds mainly as a natural seasoning rather than a staple food. Miner's pepperweed is generally safe to eat in moderation. Like other members of the mustard family, very large quantities may cause digestive discomfort in sensitive individuals because of naturally occurring mustard oils. Harvest only from clean, uncontaminated sites [2-3]. Leaves - raw or cooked[172, 177]. A hot cress-like flavour, they are used in spring and early summer, the young leaves are best[9]. Immature seedpods - a hot pungent taste, they are used as a flavouring[9]. Seed - used as a mustard-like flavouring[172]. The pungency of mustard develops when cold water is added to the ground-up seed - an enzyme (myrosin) acts on a glycoside (sinigrin) to produce a sulphur compound. The reaction takes 10 - 15 minutes. Mixing with hot water or vinegar, or adding salt, inhibits the enzyme and produces a mildly-pungent but bitter mustard[238].

Analgesic  Kidney

The leaves have been chewed in the treatment of headaches[257]. An infusion of the plant has been used in the treatment of kidney problems[257]. It has also been used as a dietary aid for a person trying to lose weight[257].

Wildlife Value: The flowers provide nectar and pollen for insects, and small birds eat the seeds. The foliage also supports several insects associated with the mustard family. Pollinators: The many small flowers attract bees, hoverflies, parasitic wasps, and other beneficial insects.
