Gladiolus

Showy summer bloomer excels as a cutflower. Each stalk is covered with 10 or more open funnel-shaped flowers that bloom from bottom to top. Named for their sword-like leaves; a gladiolus is a small Roman sword. Each stalk blooms for about a week, roughly 8 weeks after planting.

Growing Gladiolus

  • After the last spring frost, plant corms in full sun 5" deep and 8" apart. Stagger plantings for a long season of blooms: First planting in early to mid-May, then again every two weeks through mid June. This schedule will keep the flowers coming July through August.
  • Hill or stake the corms at planting time to keep the plants from keeling over when the foliage and flower spikes get top heavy.
  • Mulch with straw to retain even moisture and prevent weeds.
  • Cut the stalks when 2–3 blossoms have opened, taking care to spare the leaves, which feed the developing corm.
  • To overwinter, dig corms after the tops have died, discard the old one, clean the new one, allow it to dry off, and store them in paper bags in a well-ventilated cool (35–45°) dark dry place.
