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.[2][3] The species is sometimes cultivated in other regions as an ornamental.[4]
Allium scilloides produces bulbs along an underground rhizome, each bulb round to egg-shaped, up to 2 cm across. Flowers are bell-shaped, about 7 mm across; tepals white, pink or purplish with green midribs; anthers purple; pollen white to gray.[2][5][6][7][8]
