How to Grow and Care for Gladiolus — The Elegant Sword Lily

Gladiolus is a stunning ornamental herbaceous plant admired for its vibrant and diverse colors. Belonging to the Iridaceae family, this flower is known for its distinctive sword-like shape—hence the name Gladiolus, derived from the Latin word gladius meaning “sword.” Originating from South Africa, the Gladiolus entered Europe around 1720, flourished in the Netherlands, and later spread across Asia in the 2000s.
