There is a great variety of gladiolus flowers, whose main classification is based on size and mode of bloom. The most common is large-flowered hybrids, with tall spikes and bold colors. Dwarf types are shorter and can be used in small gardens or containers. Butterfly gladiolus are also available that have ruffled and exquisitely colored petals. All types have their own visual appeal, and gladiolus is a flexible landscaping, bouquet, and decorative item in formal and informal gardens.
