About
Hastingsia bracteosa is a rare species of flowering plant in the agave subfamily of the asparagus family known by the common name large-flowered rushlily. It is endemic to Oregon in the United States, where it is limited to a twelve-mile stretch of the Illinois Valley in the southwestern part of the state.
This plant grows from a dark-coated bulb and produces gray-green leaves up to 52 centimeters long. The slender, erect scape grows up to 87 centimeters tall. At the top is an inflorescence which is a raceme of many flowers. Each flower has tepals roughly 1 centimeter long. Some plants produce white flowers and some purple, and where they occur together they can cross to produce pink flowers. White-flowered plants generally occur in the northern part of the species' very small range, and purple plants grow in the southern end, the two separated by a single meadow where they mix.
