Gladiolus 'Circus Color' Bulbs

'Circus Color' is a large-flowering gladiolus that commands attention with its vivid, carnival-inspired hues of yellow and blue. Towering 36 to 48 inches tall, its flamboyant flower spikes rise above a bed of strappy green foliage, bringing vibrant energy to garden beds, borders, and containers. Loved by pollinators, including bees, butterflies, and hummingbirds, 'Circus Color' adds lively charm to any outdoor space. These stunning blooms are also exceptional cut flowers, perfect for dynamic bouquets and mixed floral arrangements.

A Gladiolus x hortulanus variety, commonly called gladiolus, glads, or sword lilies, 'Circus Color' is a perennial in Zones 7-10. For the most dramatic displays, plant bulbs in groups or masses in pollinator gardens, cutting gardens, or mixed flower beds. In windy areas, staking may be required to support the tall flower spikes.

'Circus Color' gladiolus thrives in sunny to partially shaded spots with rich, porous soil that drains well yet retains adequate moisture. Amend sandy or clay-heavy soils with organic materials like peat moss or bark to improve structure and water retention. Fertilize lightly after planting and again in summer with a balanced plant food. Water thoroughly at planting and consistently during growth and bloom to keep the roots hydrated. Mulch around plants to conserve soil moisture and regulate temperature.

Plant bulbs in spring after the last frost, spacing them 4 to 6 inches apart and planting them 4 to 6 inches deep. For extended blooming, stagger plantings every two weeks. After flowering, allow the foliage to grow until it browns or frost approaches. Dig up, clean, and store the corms in a cool, dry place (40-50°F) for winter.
