| Lewisia rediviva | |
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.[1]
The genus Lewisia was moved in 2009 from the purslane family (Portulacaceae) with adoption of the APG III system, to the family Montiaceae.

The specific name rediviva is given by Pursh in consequence of the root, long preserved in the herbarium, and apparently dead, having been planted, revived in a garden in Philadelphia.
