Plant Description
Native perennial herb.
Leaves are palmately compound and composed of 5 to 10 narrowly oblong leaflets, each leaflet up to 7 cm. in size. Stems and both surfaces of leaves are covered in fine, whitish hairs.[1]
Pappilonaceous flowers vary in color and may be white, yellow, purple, or blue and white. Flowered are whorled in racemes up to 4.5 dm long. Flowers have an upcurved glabrous keel, with slender wings which expose lower half of keel.[2]
Pods are 2-5 cm, silky.[3]
Bloom Period
May to July [4]
Distribution
Puget Trough southwards, along West Cascades in Washington and Oregon, to California and western Nevada.[2]
Habitat
Grasslands and prairies from the lowlands to moderate elevations.[4]
Uses
Because of the capacity to fix nitrogen and grow quickly, Lupinus albicaulis is useful for soil stabilization and improving soil fertility.[5]
Benefits hummingbirds and butterflies (larval host). Low palatability for browsing and grazing animals although small animals use it for cover. Birds eat seeds. Seeds toxic if eaten in large quantities. [6]
Seed
Seed sample from: 2011
Average Measurement: 5.7 x 4.4 x 2.1
Measurement Range: L: 5 - 6.5, W: 4 - 5, D: 1.5 - 2.5
Features
Color: Seeds are mostly off-white, tan, or gray with darker brown or tan mottling. Speckles tend to be heavier at seed edges leading to a darkened appearance.
Surface: Seeds smooth and glossy with some concave pitting.
Latitudinal Cross Section: elliptical 
Longitudinal Cross Section: elliptical 
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.
