What does bitterroot mean?
Bitterroot is a noun naming a low-growing perennial wildflower, Lewisia rediviva, native to the dry open country of western North America. Each spring it produces striking pink or white cup-shaped blossoms that open on short stems rising almost directly from the ground, giving it a distinctive, almost stemless appearance. Its common name comes from its large, fleshy taproot, which has an intensely bitter taste but is highly nutritious and was long a valued food among Indigenous peoples such as the Salish, Kootenai, and Nez Perce, who dug, cleaned, and dried the roots each season. The plant holds cultural significance as the state flower of Montana, and the nearby Bitterroot Range and Bitterroot River were named for it. Botanically notable for its ability to survive desiccation and revive with moisture — reflected in its species epithet rediviva, meaning 'brought back to life' — bitterroot appears today mainly in regional, botanical, and place-name contexts rather than in casual conversation.
nounA perennial herb (Lewisia rediviva) native to western North America, bearing pink or white flowers and a starchy, intensely bitter root that was an important food source for Indigenous peoples; it is the state flower of Montana.
- The plant Lewisia rediviva, a low-growing perennial with showy pink to white flowers, native to dry regions of western North America and the state flower of Montana.
- The thick, starchy, strongly bitter root of this plant, traditionally dug, dried, and eaten by Indigenous peoples of the American West.
"In early summer the hillsides above the valley were carpeted with the rose-pink blossoms of bitterroot."
"The Bitterroot Mountains take their name from the small flowering herb that grows throughout the region."
"Salish and Kootenai gatherers harvested bitterroot each spring, peeling and drying the roots for winter use."
Regular plural; typically used when referring to multiple plants or specimens rather than to harvested roots.
"The rocky slopes were dotted with dozens of bitterroots in full bloom."
Bitterroot's scientific name, Lewisia rediviva, means 'brought back to life' — the plant can revive from a dried, apparently dead state when watered.

Etymology of bitterroot
The word bitterroot is a straightforward English compound of 'bitter' and 'root', coined by English speakers to describe the acrid taste of the plant's large taproot. The term arose during the period of Euro-American exploration and settlement of the American West in the nineteenth century; Meriwether Lewis collected the plant on the Lewis and Clark Expedition, and the genus name Lewisia honors him. The species name rediviva is Latin for 'revived', referring to the dried plant's ability to spring back to life with moisture. The word itself derives transparently from Old English 'biter' (bitter) and 'rot' (root), sharing origins with other Germanic compounds.
How bitterroot is actually used
The word is most often encountered in proper-name constructions such as the Bitterroot Range or Bitterroot River in Montana, named after the plant. Outside botany and the American West it remains relatively uncommon in everyday speech.
