The Fidelio, 'Gladiolus Fidelio', a spring planted corm, exhibits magnificent lavender flowers. Gladiolas are also commonly called Sword Lily or Corn Flag. To extend the time of flower availability of your Glads, plant in two week intervals from early spring through June. 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.
