About Great Camas

Great Camas is a large native western North American bulb hardy in USDA zones 4-8, producing tall 2 to 4 foot spikes of starry blue, purple, or white flowers in late spring. Native to moist meadows and prairies from British Columbia to northern California, it thrives in heavy clay soils that defeat most bulbs. A premier American native bulb for perennial borders, prairie plantings, and rain gardens across the continent.

History

Illustrated historical scene for Great Camas

Camassia leichtlinii grows in moist meadows and oak savannas across the Pacific Northwest. Sereno Watson of Harvard's Gray Herbarium described it in 1885, naming it for Max Leichtlin, a Baden bulb specialist. For at least 8,000 years, Pacific Northwest Indigenous peoples including the Kalapuya, Nez Perce, and Coast Salish pit-roasted camas bulbs as a major carbohydrate source; the bulbs develop sweet caramel flavors through long slow cooking.

Women managed vast prairies with controlled burns to maintain camas populations, creating landscapes the Lewis and Clark Expedition described in 1806 as looking like 'lakes of fine clear water'. European settlement converted most camas prairies to agriculture.

Horticultural cultivars include the taller 'Semiplena' (double cream) and the subspecies suksdorfii 'Caerulea' (deep blue). Beware: the white-flowered 'death camas' Zigadenus species are highly toxic. Introduced to European gardens in the 1850s by Henry Leichtlin and rediscovered by American native-plant gardeners in the late 20th century.

Symbolism & meaning

What It Symbolizes

Great Camas rises in tall starry blue spikes above the spring meadow, a prairie spire visible across the long grass. Its deeper meaning is native heritage, for its bulbs were a staple food of Pacific Northwest tribes for millennia, gathered, pit-roasted, and traded across great distances. To grow camassia is to remember that what we now plant for ornament was once, and remains, the sustaining food and cultural inheritance of the people who knew this land first.

  • Prairie spire — tall starry spikes rise above meadow grasses

Where the Name Comes From

'Camassia' from the Nez Perce 'quamash', the traditional name for the edible bulb; 'leichtlinii' honors Max Leichtlin (1831-1910), German horticulturist.
