Mountain Ash {Sorbus L.) 



Mountain ash is among the most attractive shrubs in the western national 

 parks. The separate leaflets, the large somewhat flat-topped clusters of white 

 flowers, and the conspicuous red berries easily distinguish the plants as be- 

 longing to the mountain ash genus. They are attractive at most any time 

 of the year, and especially in the autumn when the leaves turn a beautiful 

 red color. Birds and squirrels eat the fruits and the foliage is browsed to 

 some extent by the larger animals.
