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.[1] 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

Lupinus albicaulis, photo by Lisa Hintz

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 LUAL-lat.png

Longitudinal Cross Section: elliptical LUAL-long.png

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.
