High Voltage electrifies the garden with bright, sunny yellow semi-double blooms that hold their color beautifully. Part of the hardy, own-root Easy Elegance series, it flowers from spring through fall with a light, sweet fragrance. Plant it in full sun, where it reaches three to five feet and resists disease with very little care. The cheerful yellow flowers light up borders, hedges, and mixed plantings. Bred for northern toughness, it shrugs off cold winters. For carefree, high-wattage yellow, High Voltage delivers a jolt of joy.
