The propagation of these flowering shrubs through vegetative means, specifically utilizing excised portions of the parent plant, allows for the creation of genetically identical offspring. This technique, involving the detachment and rooting of a stem or leaf section, provides a method of replicating desirable traits and characteristics present in a particular rhododendron cultivar.
This method offers several advantages, including the preservation of specific flower colors, growth habits, and disease resistance. Furthermore, it can accelerate the time to flowering compared to starting from seed. Historically, this approach has been crucial in horticulture for maintaining and expanding collections of superior rhododendron varieties, especially those difficult to reproduce through seed.
