'Wild Blue Yonder' features ruffled, wavy flowers up to 4-1/2 inches in diameter in a breathtaking color the Rose Society describes as velvety, warm wine purple layered onto rich lavender. The scent is citrus blossom and rose. This grandiflora rose has excellent disease resistance and grows medium-tall, upright and bushy with glossy, deep-green foliage and medium-long stems. A clear winner.
