Description
General: Glabrous perennial herbs from an onion-like bulb, the simple stem 2-5 dm. tall. Leaves: Leaves mostly basal, linear, keeled, 1-3 dm. long and 3-6 mm. broad; cauline leaves strongly reduced upward. Flowers: Inflorescence a raceme (but sometimes the raceme branched at the base) up to 1.5 dm. long, the flowers all perfect; perianth white to cream-colored, bell-shaped; tepals 6, unequal, the outer 4.5-5 mm. long, short-clawed, the inner about 0.5 mm. longer with a narrower, slightly longer claw; the gland at the base of each tepal yellowish-green, broader than long; stamens 6, about equal to the tepals; styles 3, distinct, 2-3 mm. long. Fruit: Capsule 8-15 mm. long.
Bloom Period
April-July
Distribution
British Columbia to Baja California, east to the Dakotas; var. venenosum more common west of the Cascades in Washington, var. graminaeum common in Eastern WA.
Habitat
Ecological Setting Coastal bluffs and prairies, and moister areas of shrub-steppe and mountain meadows
Uses
First Nations-Used as a violent emetic, sometimes mixed with blue flag; poultice of mashed roots applied to rheumatism, boils, bruises, sprains, sore legs, burns, swellings, rattlesnake bites, and broken bones to speed healing; mashed roots sometimes used as an arrow poison
Propagation
This plant is highly toxic and can be weedy or invasive according to the authoritative source
Seed
Basic Explanations and Assumptions:
The dimensions for the seeds are length x width x depth. The location of the hilum is used as the base of the seed, and the length is measured from hilum to the opposite apex. Where a style is present, the length is measured from the hilum to the bottom of the style. Width is measured at a right angle to the length at the widest part. Depth is measured at a right angle to the intersection of height and width lines.
Measurements included are the mean average for each measurement of ten separate seeds.
All measurements in millimeters unless otherwise noted.
