Habitat types and community types using longflower snowberry as a climax indicator are limited. Longflower snowberry is an important forage species on the xeric sites it occupies and is utilized by both big game and livestock. Over much of its range, it is often the first browse species to leaf out. The seeds are eaten by a number of species of birds, especially grouse, pheasant, and quail. Palatability of longflower snowberry is highest in the early spring and declines throughout the summer and fall.
Longflower snowberry is a very useful shrub for establishing cover on raw and severe sites.
Once established longflower snowberry is very persistent. Sites can be revegetated using wildlings or transplants. Transplants are easily obtained by pulling up small rooted portions of plants in the early spring before leaf growth has begun. Commercial seed may be dried or cleaned. Longflower snowberry is monoecious.
