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.

Description

Glabrous annual herb, growing from a taproot with terminal heads of purplish flowers, up to 70 cm tall.[2] Stems spreading to erect, 1 to several.[3] Leaves alternate,[3] trifoliate, petiolate with narrow leaflets to 4 cm long, serrulate; stipules large, ovate, lacerate.[2] Inflorescences head-like, involucre greater than 3 mm,[4] 1-3 cm wide with 6-60 flowers.[3] Flowers papilionaceous; calyx shiny,[5] 5-lobes equal in length to tube;[2] corolla 5-merous with banner, wings and connate keel, purple, 8-15 mm;[5] stamens 10, diadelphous; pistil simple, superior ovary becoming a 1 to 2-seeded capsule.[4]

Bloom Period

April-July[2]

Distribution

British Columbia south to California; in Washington, west side of the Cascades and east along the Columbia River.[2]

Habitat

Low to moderate elevation grassy hillsides, balds, prairies and meadows.[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. [6]

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.[7]

Seed

Trifolium willdenovii 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 Lat TRWI.png

Longitudinal Cross Section: elliptical Long TRWI.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.
