Abstract
A new and distinct cultivar of winter hardy hibiscus plant named ‘Pink Comet’ is the result of a unique hybridization. This new and distinct cultivar is characterized primarily as to novelty by its tropical aspects, its extreme cold hardiness to Zone 4, its medium-sized, thick-textured, pink flowers with pale pink to white reverse having multiple markings of red and pink on both sides of the petals and its shiny green leaves and unusual compactness of about 2 feet, its vigorous and uniform growth habit, and its floriferous nature from midsummer until frost, and its genetic achievement as a cross between a tropical and hardy Hibiscus.
