Narrative
The Maybell Source select class Antelope bitterbrush is a creeping or decumbent ecotype having propensity for layering; that is, a decumbent branch may root from adventitious buds where it contacts the ground. Low-growing, layering ecotypes are common on sandy loam soils in southeastern Idaho, and in silt and clay soils in central Utah. The Maybell source is 24-40 in in height and generally 36-52 in wide. Leaves are persistent with the small, young, winter leaves turning purplish red but remaining over winter. The leaves are small, 6-19 mm, wedge shaped, and three-lobed. Leaves vary in color from gray green to bright green. It flowers profusely with mostly yellow blossoms. The Maybell Source is recommended for rangeland and reclamation seedings. It is useful for spring and winter browse for domestic livestock, antelope, deer, elk, and small mammals. It is suitable for erosion control on light textured soils where wildlife presence is acceptable. The low-growth and attractive appearance makes it promising as a low maintenance landscaping species for xeriscape. Antelope bitterbrush is one of the most important native browse shrubs in the western United States. Antelope bitterbrush contains resins and maintains a heavy canopy that burns readily and may contribute to range fires.
