Gladiolus Blue Isle

The Blue Isle, 'Gladiolus Blue Isle', a spring planted corm, exhibits magnificent dark blue flowers with a light blue heart. Gladiolas are also commonly called Sword Lily or Corn Flag. Plant in groups of six or more in the garden, or grow lots of them for cuttings in a bed. To extend the time of flower availability of your Glads, plant in two week intervals from early spring through June. They make striking accents in a mixed border. Glads are easy to grow and like to be in full sun and in well drained soil. Increase water and fertility when flowers begin to develop, then plant 4 deep in clay soils, 6 deep in others the deeper the planting the less need for staking. In frost prone areas, dig them when the leaves turn yellow, dip them in a fungicide, and store in a dry frost free location over winter.
