    Purshia mexicana

    Mexican cliffrose

    Mexican cliffrose shrubDescription: Mexican cliffrose is the southern cousin of Purshia tridentata
    (antelope bitterbrush) but is taller with pleasantly fragrant evergreen foliage
    and a gnarled form that can grow to six feet tall.

    The creamy white to pale yellow honey-scented flowers that cover the plant in late spring give way to long feathery seedheads in early to mid summer. The small dark green, deeply lobed leaves that cover the branches provide a nice contrast to the five-petaled, yellow-centered flowers.

    Mexican cliffrose occurs throughout the southern regions of the Intermountain West and has great potential for use in low-water landscapes.
