Plant Common Name

General Description

Native to valleys of the northwestern United States and southern British Columbia, this hardy bulbous perennial bears steepled clusters of starry flowers atop tall leafless stems in late spring. The creamy-white or blue blooms have six pointed segments. As they wither the blooms clasp the developing seed pods. The clumps of strap-shaped, keeled, green to gray-green leaves go dormant in summer. The leaves and flower stalks grow from large bulbs with dark tunics. The cultivar 'Blue Danube' has deep blue flowers; 'Semiplena' bears double, linen-white blooms.

Plant the bulbs three times as deep as they are wide. They grow and flower best in full to partial sun in well-drained, humus-rich soil. Though this plant prefers steady moisture in late winter and spring it will not tolerate waterlogged soil. Narrow in stature, it looks best when planted in groups. Given favorable conditions and left undisturbed, large camas persists and increases for years. Pair it with plants such as hardy geranium that will cover the withering leaves.
