Add drama and flair to the garden with this showy hybrid gladiolus. Volbeat features deep blue-purple flowers and black buds. We selected Hybrid Gladiolus Volbeat for its color, garden performance and value. Growing 3-4′ tall, its swordlike foliage and tall flower spikes make striking accents in the flower border. They’re also very showy cut flowers. To enjoy blooms for many weeks, plant bulbs at two-week intervals from early spring until the end of June. Glads are easy to grow, requiring only full sun and good drainage. Deer tend to pass them by. Lift in the fall in zones 3-7.
