|discussion=<p><i>Eriogonum congdonii</i> is an elegant subshrub restricted to the mountains of central-northern California (southern Siskiyou and northern Trinity counties). It is worthy of serious consideration as a garden introduction even though it typically occurs on nearly raw, greenish-black serpentine outcrops. In that setting, the olive green leaf blades, the bright green and nearly glabrous flowering stems and inflorescence branches, and the dense clusters of rich sulphur-yellow flowers make a beautiful contrast.</p>
