Like their traditional cousins, Gladiolus byzantinus are prized for the spectacular cut flowers they produce. For longer lasting arrangements, make sure to cut the spike when only one to three florets are open. Planting them at intervals will allow you to enjoy them in your arrangements throughout the season.
