Rhododendrons have a wide range of lifespans depending on the species, variety, and growing conditions. Generally, most rhododendrons live anywhere from 10 years to several decades with proper care. Some specimens have been known to live over 100 years, especially in ideal conditions
. Certain species, like the Catawba rhododendron, can exceed 100 years of age. In natural or well-maintained environments, rhododendrons can live for hundreds of years, although this depends on factors such as soil quality, moisture, drainage, and disease management
. The leaves of rhododendrons typically live 2-3 years before naturally shedding, but the plant itself can persist much longer if healthy
. Rhododendrons require good drainage and acidic soil to thrive; poor conditions or root damage can shorten their lifespan
. In summary, while many rhododendrons live 10-20 years or more, with optimal care and conditions, some can live well beyond 100 years, making them long- lived shrubs or small trees in gardens and natural settings
