Appeal: Oso Berry, or Indian Plum, is one of the first flowering native shrubs to herald the approach of spring.  Its white, fragrant, drooping flowers, appear in March, before many species leaf out.  The flowers give rise to berries that ripen and turn purple in June, which provide a favorite source of food for many bird species.  This plant is relatively easy to establish.  It does very well along streambanks and wetland areas, as well as forested areas where there is some sunlight.

Helpful Tips: As with any new planting, it should be watered during the dry season for the first 1-2 years until it becomes established.  Plant 4-6 inches apart and expect some mortality.
