Gladiolus Rainbow Collection – 50 Premium Gladiolus Corms
Fill your garden with tall, dramatic flower spikes in a spectacular array of colors with this collection of 50 gladiolus corms. Featuring an elegant contrast of pink, purple, and white gladiolus mixed together, this collection creates a stunning display whether planted in rows, clusters, or mixed borders. Each package includes 30 pink, 30 purple, and 30 white gladiolus for incredible variety.
Planting Instructions: Plant gladiolus corms in spring, 2 weeks before the last expected frost through early summer. For continuous blooms, stagger plantings every 2 weeks. Plant corms 4 inches deep and 6 inches apart with the pointed end up. In windy areas, plant slightly deeper (5–6 inches) for better stability, or provide support stakes.
Growing Conditions: Gladiolus prefer full sun and well-drained, sandy loam soil. Hardy in USDA Zones 7–10 as perennials; in colder zones, dig corms 6–8 weeks after blooming and store in a cool, dry location. Water regularly during the growing season (1 inch per week). Avoid overhead watering to prevent fungal issues.
What to Expect: Each gladiolus produces a stunning flower spike reaching 3–4 feet tall, covered in ruffled blooms that open from the bottom up over 1–2 weeks. Blooms appear 70–90 days after planting. The mix of pink, purple, and white creates a romantic, cottage-garden feel. Gladiolus are among the best cut flowers — cut when the bottom 2–3 flowers are open for arrangements that last up to 10 days.
