Common Name: Mountain Tansy Mustard
Descurainia incana is a Annual/Biennial up to 1.00 metres tall.
It is harvested from the wild for local use as a food and medicine
Western N. America. A casual in Britain[
Found in many habitats at lower mountain elevations[
We have almost no information on this species but since it is a casual in Britain there should be no problems in cultivating it here and it is probably not too fussy about soil or situation. We suggest growing it in a dry to moist soil in a sunny position.
There is some confusion as to the correct name for this species with some authorities using the name D. richardsonii.
Young leaves - cooked. A bitter taste[
Seed - raw or cooked[
]. The seed can be used as a mustard substitute in soups, stews etc. It can be roasted, ground into a powder then mixed with water to make a fine batter and drunk[
]. The seed is also ground into a meal and mixed with cereal flours when making bread, or as a thickening for soups etc[
The plant has been used as a lotion for parts of the body that have become frozen in the cold and also as a lotion for sore throats[
]. No more information is given, but it is likely that the crushed seed was used for this since, being similar to mustard, it will probably have a rubefacient effect upon the skin, drawing more blood to that area of the body and thereby heating it[
The plant is mashed and applied to bad cuts[
Seed - sow spring in situ.
