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.
Information concerning regenerative processes in longflower snowberry is scant.
Although many members of the Symphoricarpos genus are highly rhizomatous, the extent to which this habit is developed in longflower snowberry is unclear. Fruits are white, berrylike drupes containing two, seedlike nutlets which ripen in the fall. Since no abscision layer is formed on the pedicle, fruits can persist on shrubs for up to two seasons before falling to the ground. Seeds do not remain viable for extended periods in nature. Germination begins in the early spring as soon as the soil thaws.
