Narrow Leaved Brickellia
Brickellia oblongifolia Nutt.
The glands on the Thoroughwort are covered with fine hairs. Being a perennial herb or subshrub, it is 4 to 24 tall, generally with many stems from near the base. The leaves are essentially sessile, sitting directly on the base without support. The shape of the leaves is lance-linear to oblong or elliptic-oblong and are 1/3 to 1 inch long and up to 1 inch wide. The heads terminating at the end of the branches are relatively large with flowers having reputedly 40-50 in each head. It is in bloom from June through August. It prefers shrub-steppe and sagebrush hillsides in dry, often rocky places, in the foothills and lowlands to 2400 or even 2700 mountain elevations. It is found throughout the Rocky Mountain area and is reported by Cronquist as found in Pocatello, Idaho.
