Happy Days blooms with a 5-7" brightly-colored, ruffly single. Its bush is one of HVH's most beautiful, with full foliage, symmetrical shape, that looks just as beautiful in the winter as it does in the summer. It's floriferous and a great addition to any patio, house, or yard. Brand new from HVH this year!
