Abstract: A new and distinct cultivar of winter hardy hibiscus plant named ‘Old Yella’ is the result of a unique hybridization. This new and distinct cultivar is characterized primarily as to novelty by its extreme cold hardiness to Zone 4, its large, thick-textured, pale yellow flowers and its green-leaved plants with bright yellow buds before onset of flowering, its vigorous and uniform growth habit, and its floriferous nature from midsummer until frost.
