Description

Annual, erect herb with axillary blue to pinkish flowers, up to 50 cm tall.[2] Stem simple to branched, sparsely pubescent.[2] Leaves opposite, lower leaves long-petiolate, often toothed, upper leaves linear, sessile.[3] Flowers zygomorphic, pedicelate, 9-17 mm;[4] calyx 5-lobed, subequal; corolla bilabiate, tube bent at right angle to calyx, 2 upper lobes, 3 lower lobes; stamens 4, didynamous; stigma capitate,[5] ovary 2-carpellate, superior,[6] becoming a 4-sutured capsule.[2]

Bloom Period

April - June[2]

Distribution

West of the Cascade crest, British Columbia to California and in the Columbia River Gorge.[2]

Habitat

Low to mid elevation open areas, moist or dry.[2]

Propagation

Sow seeds in both the fall and early spring for the maximum season of flowering.[7]

Seed

Seed sample from: 2010

'Average measurement: 0.7 x 1.5 x 1

Measurement range: L: 0.5 - 0.9, W: 1 -1.6, D: 0.7 – 1.1

Features

Color: Seed bright red with a large, white, elliptical shaped depression on the longer face of the seed that is the hilium.

Syrface: Seeds matte and bumpy, with some wrinkling around the hilium depression.

Could be confused with: Collinsia parviflora.

Latitudinal cross section: elliptical COGR lat.png

Longitudinal cross section: irregular

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.
