Distribution: Occurring east of the Cascades crest in Washington; Washington to California, east to Montana, Idaho, and Nevada.

Habitat: Sandy or rocky soils, sagebrush desert to ponderosa pine forests.

Flowers: May-July

Origin: Native

Growth Duration: Perennial

Conservation Status: Not of concern

Pollination: Bumblebees, bees, flies, butterflies, beetles, wasps

Description:
General:

Perennial with woody stems up to 1 dm. long, the several flowering stems to 3 dm. tall, usually white-woolly throughout and more or less freely branched.

Leaves:

Mostly basal, the blades elliptic to ovate, 5-25 mm. long, usually white-woolly on the lower surface and less so on the top, on petioles as long to 4 times as along as the blades.

Flowers:

Flowering stems leafless, the inflorescence from open and freely branched with the involucres single at the branch tips to umbellate and the involucres somewhat clustered; with small, linear bracts at the forks of the branches; involucres narrowly cup-shaped, with 5 triangular, erect, short teeth; tepals white or cream to pinkish or yellow, 3-4 mm. long, divided nearly to the non-stipitate base, the segments oblong, the outer twice as broad as the inner.

Identification Notes:

Eriogonum strictum plants with the branched inflorescence may be separated from the similar E. niveum by the bracts at the branch joints, which are small and thread-like in E. strictum and leaf-like in E. niveum. The E. strictum plants with umbellate and somewhat compressed flower clusters may be confused with E. ovalifolium when the tight, head-like flower clusters of the latter are in umbels instead of single.

Accepted Name:
Eriogonum strictum Benth.
