The seed contains about 41% of a sweet edible oil, about 28% can be extracted from the seed in an oil press[2, 46, 61]. Of a high quality, it can be used as a substitute for olive oil[2, 183].

Madia sativa 'Molina' has water repellent foliage that is extremely difficult to wet; even with the use of a wetting agent surfactant. The foliage contains many tiny hairs also.

It appears suddenly, in patches of numerous individuals and grows prolificly; completely covering an area to a height of 30cm in only 2 weeks where there is abundant sun and rainfall. It can do this in very poor soil.

Although it does best with rainfall, it can inhabit well drained slopes and can even be found areas having arrid summers such as eastern Washington, USA. When the climate becomes persistently hot and dry, it simply shrivels up, releases its seeds for next year's growth, and disappears until then.

A brief description of its oil at http://www.ibiblio.org/herbmed/eclectic/kings/linum_oleu.html#madia

There is some confusion with another plant named "tarweed" that is found in coastal california having Latin name Hemizonia fasciculata.

Likes both rain and sun, and soil of low fertility. Typically takes over disturbed bare areas where topsoil has been removed; where few other plants will take hold. I live about 19 km south of downtown Spokane, Washington, USA. My USDA hardiness zone is 5b.
