20 Gladiolus Bulbs Mixed Colors

Gladiolus bulbs produce tall, elegant spikes of ruffled blooms in a vibrant mix of colors, including red, pink, yellow, orange, purple, and white. These classic summer-flowering bulbs are a favorite for adding vertical interest and long-lasting color to garden beds and borders.

Gladiolus are wonderful for cut flower arrangements, with stems that hold multiple blooms opening from the bottom upward. Plant the corms in spring after the last frost for blooms in mid to late summer. For best results, plant in well-draining soil in full sun and water regularly during the growing season. In colder zones, lift and store the corms before the first frost.
