Species Description
Antelope bitterbrush, a member of the Rose family (Rosaceae), blossoms with sweet-smelling yellow flowers during April and May. Along the Truckee River, look for this shrub in upland areas, away from the water’s edge. Bitterbrush survive under dry conditions by sending down a long taproot of up to 18 feet deep (Zlatnik 1999).
Though the flowers smell sweet, the leaves of bitterbrush taste bitter to the human palate (hence the name). Livestock and wildlife, however, seem to love the stuff; the leaves are high in crude protein and fat, and bitterbrush is a preferred food item of antelope, mule deer, sheep and cattle. Rodents and ants collect and cache the seeds (Mozingo 1987).

I have been told by several friends who are Master Gardeners, that Bitterbrush is very invasive and highly flammable (like creosote). However, I have been unable to find any such facts when I search for information on this plant. My concern is whether or not it is a fire hazard, as I have several plants within 20 feet of my house. Should I remove them? If so, why isn’t there any general information regarding this? Thank you in advance for a response.
Having Bitterbrush around is like having open jars of gasoline just waiting to ignite. Once started, it burns about the same, especially when green!
