I have been curious about an aspect of propagation by cuttings. What effect does this have on the longevity of the new plant? For instance, one of the touted bonuses of propagating cuttings is that you don't have to wait years for the plant to mature, a real bonus when dealing with fruit-bearing plants. But what about plants that have a short life span? An American Elderberry is supposed to be a short-lived shrub only lasting a few years. If you take a cutting from an Elderberry during the last years of its life, will the new plant have only a year or two or will the new set of roots give it an extension on life?
