Gladiolus 'Princess Margaret Rose' Bulbs

'Princess Margaret Rose' is a large-flowering gladiolus that electrifies the summer garden with a burst of tropical color. Its 36- to 48-inch flower stalks rise above an elegant fan of strap-like leaves, blooming in fiery shades of red, yellow, and orange. These ruffled, glowing blooms bring bold energy to garden beds and borders while serving as stunning florist-quality cut flowers for monofloral bouquets and mixed arrangements.

A Gladiolus x hortulanus variety, commonly known as gladiolus, sword lilies, or glads, 'Princess Margaret Rose' is a perennial in Zones 7-10. For maximum impact, plant bulbs in clusters or masses in garden beds, borders, containers, or even rock gardens. In windy areas, staking may be necessary to support the tall flower spikes.

'Princess Margaret Rose' gladiolus is easy to grow and thrives in full sun to partial shade with rich, porous soil that drains well yet holds sufficient moisture for healthy growth. Amend sandy or clay-heavy soils with organic materials like peat moss or bark for better water retention and drainage. Fertilize sparingly after planting and again in midsummer to encourage vibrant blooms. Water deeply at planting and regularly throughout the growing season to keep the soil evenly moist. Mulch around the plants to maintain 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. Lift the corms, clean and dry them, and store them in a cool, dry location (40-50°F) for winter storage.
