Rosaceae (Rose Family)
USDA Symbol: cemo2
Alder-leaf Mountain Mahogany is an 8-20 ft. shrub or small tree with very attractive, almost-evergreen leaves - dark green on top and fuzzy silver underneath. Non-showy flowers are followed by feathery, silvery-white fruits, occuring from May to November.
Variety glaber is known by the common names Birchleaf Mountain Mahogany and Hardtack, among others. It is a common shrub in chaparral vegetation, sprouting after fire. It is also an important browse plant for deer, cattle, and sheep. The common and scientific names both refer to the resemblance of the leaves to those of shrubby birches. It is called Hardtack perhaps from its ability to withstand cutting, fire, drought, and heavy browsing. Cercocarpus, from the Greek words for tail and fruit, describes the hairy tails or plumes from the elongated flower style. These hairy fruits are carried long distances by the wind; animals harbor them in their fur, also aiding dispersal. After falling to the ground, the oddly shaped fruits twist into the soil.

Privacy hedge for South Dakota
August 08, 2008
Hi, I'm looking for something to use as a hedge. 8 foot or so tall offering semi privacy all year. I like dogwoods but loss of leaves in the winter makes me skeptical. Boxwood would be interesting...
