These cormose perennials are grown for their showy spiked flowers , which open up from the bottom upwards . Foliage is shoulder strap - like and vertical . Gladiolus take care best when planted in large groups . It is vulgar to stake them . Soil should be fertile and well drain and light may be full sunlight or partial shade . Hardy in zones 8 - 10 , they may be imbed in other areas as annuals or even protected with a compact level of mulch ....
