A new and distinct cultivar of winter hardy hibiscus plant named “Strawberry Swirl” is the result of a unique hybridization. This new and distinct cultivar is characterized primarily to its novelty by, its extreme cold hardiness to Zone 4, large, pinwheel-shaped, pink and white flowers and its “maple-shaped” green foliage, compactness of about 3 feet, its vigorous and uniform breaking habit and its floriferous nature from midsummer until frost.
