About

Bitterroot (Lewisia rediviva) is a small perennial herb in the family Montiaceae. Its specific epithet rediviva ("revived, reborn") refers to its ability to regenerate from dry and seemingly dead roots.

The genus Lewisia was moved in 2009 from the purslane family (Portulacaceae) with adoption of the APG III system, to the family Montiaceae.

Where it grows

The plant is native to western North America from low to moderate elevations on grassland, open bushland, forest in dry rocky or gravelly soils. Its range extends from southern British Columbia, through Washington and Oregon west of the Cascade Range to southern California, and east to western Montana, Idaho, Wyoming, northern Colorado and northern Arizona.

Uses

The thick roots come into season in spring and can survive extremely dry conditions. If collected early enough in the season, they can be peeled, boiled, and made into a jelly-like food.
