Is gladiolis an annual or perennial? Gladiolus (from Latin, the diminutive of gladius, a sword) is a genus of perennial bulbous flowering plants in the iris family – Glads actually do not grow from bulbs but from “corm” – a closely related cousin.
Do gladiolus come back year after year? Gladioli grow from corms, which are underground storage organs much like bulbs. … Gladiolus come in a riot of colors and will re-bloom every year. Northern gardeners will need to lift the corms in fall and store them through the cold season to protect the gladiolus from freezing temperatures.

Can I leave gladiolus bulbs in the ground? Dig gladiolus corms before the first hard freeze in autumn, but not until the foliage dies down after a light frost. Leave the corms in the ground as long as possible, as the green foliage absorbs sunlight, which provides energy and food to produce next year’s blooms.
