Ch’il Diilyésii dzaa
(a.k.a. broom snakeweed)

Narrow, widely spaced yellow rays and darker yellow disk flowers

Snakeweed is a woody subshrub with numerous erect ascending branches. It has small, evergreen, linear leaves and tufts of tiny yellow flowers in fall. Though snakeweed was once considered a weed of overgrazed rangelands, some research suggests that its population cycles over time are more related to precipitation patterns than to overgrazing.

Broom snakeweed provides little value to livestock and can be toxic, causing illness, death, or abortion in sheep, goats, and cattle during winter and early spring when it is the only thing green and may be consumed in large quantities.
