The outrageous colors and patterns of this Glad will grab the attention of even the most lackadaisical garden visitor. ‘Zizane’ is a large healthy corm that is at least 14cm in circumference to ensure outstanding first year performance in the cutting garden or mixed perennial border. Gladiolus is hardy in zones 8 through 10, but must be dug and saved in colder climates.
