Allium scilloides, called the fragile onion, is a plant species endemic to the US State of Washington. It has been reported from only 4 counties, all on the eastern side of the Cascade Range: Klickitat, Kittitas, Yakima and Grant. It grows on barren, gravelly slopes at elevations of 300–1300 m.[3][4] The species is sometimes cultivated in other regions as an ornamental.[5]
