Bitterroot is widespread in the western United States, ranging from Washington and California eastward to Montana (where it is the state flower), The currently accepted scientific name of bitterroot is Lewisia rediviva Pursh. There are two recognized varieties: Lewisia rediviva var. rediviva and Lewisia rediviva var. minor (Rydb.) Munz. The latter variety occurs in the mountains of Nevada and southern California. It’s distinguished by smaller flowers.

The Pacific Northwest abounds with native plants that bring beauty to the home garden while offering food and shelter to birds, bees, butterflies, and other wildlife. Showy lewisias stand out in the rock garden, and with patience, you can also propagate them in pots. While many types of Lewisia cotyledon can be found in nurseries, and in various mountains, Lewisia rediviva is found higher in the mountains of Washington, Oregon, Utah and especially Montana, the state’s plant.
