Nineleaf Biscuitroot (Lomatium triternatum) is a perennial forb found in the wild across much of western North America, from Alberta and British Columbia to California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming. This plant thrives in various habitats with light requirements, particularly full sun, and can tolerate both dry and moist conditions. It grows best in soils that are light (sandy), medium, or heavy (clay) with a pH range of 6.5–8.8. Known for its distinctive appearance, the Nineleaf Biscuitroot gets its name from the presence of nine leaves on each stem. The plant is valued both as an ornamental and for its edible root, which has been harvested by indigenous communities for use as a condiment. Its roots are often dug in early spring or late fall when they are most flavorful. Nineleaf Biscuitroot can be propagated through root division, making it relatively easy to cultivate in gardens with similar conditions. This adaptable plant is well-suited to temperate regions and can serve as an attractive addition to landscapes while providing a culinary treat. Its growth form, single crown, and moderate growth rate make it suitable for various garden settings. While primarily used for its ornamental and edible qualities, Nineleaf Biscuitroot's distinctive features such as the nine leaves per stem provide practical identification cues in the wild or garden.
