The photo above shows the inflorescence and numerous stem leaves of green rabbit-brush as seen on slopes about one mile east of Celilo, OR...............October 7, 2006.
Green rabbit-brush is a freely branched shrub to 12 dm tall. The stems are erect, with brittle twigs. The stems are glabrous with stiff spreading hairs. The leaves are linear to linear-oblong, green, and lack hairs. The leaves are curled or crisp-margined and range from 1-6 cm long and 0.5-10 mm wide.
The yellow flower heads form cymose clusters at the branch tips. The flower heads are discoid and narrow. The involucre is 5-8 mm high, and the disk corollas range from 4.5-7 mm long. Green rabbit-brush flowers from late summer into fall.
Often found with sagebrush and juniper in dry open places in the valleys, plains, and foothills. It may occasionally be found to moderate elevations in the mountains.
From extreme southern British Columbia south along the east edge of the Cascades to southern California, east to Idaho and south to northern New Mexico and Arizona.
In the Columbia River Gorge, Chrysothamnus viscidiflorus var. lanceolatus may be found between the elevations of 200'-500' from just east of The Dalles and in many locations to the east in the gorge.
