Description
Annual herb from a taproot; stems 1 to several, spreading to erect, glabrous, 10-70 cm long/tall. Alternate, palmately compound; leaflets 3, linear to lance-oblong or elliptic, 1-4 cm long, the margins usually finely bristle-toothed; stipules egg-shaped, bristle-tipped, the upper jaggedly toothed, 1/3-1/2 as long as the leaflets. Inflorescence a head-like, stalked, axillary cluster of 6 to 60 pea-like flowers, the heads 1-3 cm wide, set in wheel-like, irregularly and jaggedly toothed involucres; corollas lavender to purple, 10-13 mm long; calyces 6-10 mm long, shiny and often purplish, the tube 15- to 25-veined, the lanceolate teeth slightly shorter than the tube, bristle-tipped, entire or with 2 teeth flanking the base of the bristle. Fruit are pods; seeds 1 to 2. [1]
Bloom Period
April-June
Distribution
West side of the Cascades and east along the Columbia River in Washington; British Columbia south to California. [2]
Habitat
Grassy hillsides, balds, prairies and meadows at low to moderate elevations. [2]
Uses
Seeds used for food; Young, tender plants eaten uncooked as greens; Raw or steamed buds eaten before plant bloomed; Steamed, dried leaves soaked in water or boiled before eating in winter. [2]
Propagation
Seeds are germinated during late winter and early spring months in a shadehouse were they remain for several weeks. Seeds are directly sown into flats filled with a 1 inch layer of special seed germination mix of 1:1 (v:v) Sunshine Professional Growing Mix and sand on top of 4:1:1 (v:v:v) peat, perlite, and organic compost.
Seed
Seed sample from: 2011
Average Measurement: 1.6 x 1.1 x 1.1
Measurement Range: L: 1.5 - 2, W: 1 - 1.3, D: 1 - 1.1
Features
Shape: Flattened egg shape. Hilum is small circular divot seated between a protruding lobe.
Color: Seed background gray/brown, sometimes speckled with dark brown.
Surface: Smooth and glossy.
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.
