Gladiolus 'Passos' Bulbs

A captivating beauty, 'Passos' is a large-flowering gladiolus that adds a refined touch to any garden. Reaching an impressive height of 48 to 58 inches, its stately flower stalks are adorned with lavender blooms accented by random purple stripes on the petal edges and striking purple throats enhanced by a hint of red. Rising above long, sword-like foliage, the blooms open sequentially from the bottom up, creating a lasting display of sophisticated color. Florist quality, these striking flowers are perfect for monofloral bouquets and mixed floral arrangements.

A Gladiolus x hortulanus variety, commonly known as gladiolus, glads, or sword lilies, 'Passos' is a perennial in Zones 7-10. For a truly impressive display, plant 'Passos' in groups or masses within garden beds, borders, containers, or rock gardens. In windy areas, staking is recommended to support the tall flower stalks.

'Passos' gladiolus is low-maintenance and thrives in sunny to partially shaded spots with rich, well-draining soil. Amend sandy or clay-heavy soils with organic materials such as bark or peat moss to improve water retention and drainage. Fertilize sparingly after planting and once more during summer to encourage healthy growth and vibrant blooms. Water deeply at planting and consistently during the growing and blooming periods, ensuring the soil remains moist but not waterlogged. Apply mulch to retain soil moisture and regulate temperature.

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