Plant Profile : Mountain Mahogany (Cerocarpus montanus)

Also known as alder-leaf mountain-mahogany, alder-leaf cercocarpus, and true mountain-mahogany, this mostly deciduous long lived shrub or small tree grows in chaparral scrub, and on mesas and the lower foothills from Montana, Idaho, and South Dakota south to northern Mexico.   It is a member of the rose family, Rosaceae, that also includes cherry, almond, and lady’s mantle.  The plants  have open branching with mahogany red to brown stems that can be fissured or scaley, and can grow up to 20′ tall, but are usually 5-12′  tall due to wild life browsing. The leathery, lanceolate to obovate leaves range in length from 0.4 to 2″ and are prominently veined and may be coarsely toothed.  They are green on the top, hairy white on the underside until fall when they turn russet.  In early summer, insignificant flowers appear singly or in cluster of up to 12.  The flowers lack petals but have yellowish white sepals forming a tube with 5 lobers and give way in the fall to fruit with a silky,  silvery white plume that is 2-5″ long.  A shrub covered with fruits and their plumes is especially attractive when backlit.   Plants are very drought tolerant and if  pruned hard to promote dense growth can be used as a hedge or screen.  The genus name, Cercocarpus, comes from the Greek word kerkos meaning a tail and karpos meaning a fruit and refers to conspicuous fruit.  The specific epithet, montanus, comes from the Latin word mons, meaning mountain, and refers to the native habitat of the plant.
