The heads are numerous with both disk and ray flowers. The disks are dark brown or reddish-brown, and the rays are yellow-orange (1-2 cm long). The base of the rays are often marked with orange. The involucre is smooth, 6-10 mm tall, with linear to lanceolate bracts.

Columbia coreopsis is a native of the northern Great Plains, from Saskatchewan to South Dakota.

In the Pacific Northwest, it is found along the Columbia River (from British Columbia, northern Idaho, and western Montana) downstream to Portland, OR), and several of its tributaries (the Okanogan, Spokane, and Clark Fork Rivers). It is found throughout the Columbia River Gorge east of Portland.
