Gladiola (Gladiolus) Corms

Tall, elegant spires of summer colour.

Gladiola are beloved for their striking vertical blooms — dramatic flower spikes lined with ruffled blossoms that open from bottom to top. They bring height, structure, and bold colour to gardens and bouquets alike.

Available in nearly every shade imaginable — from soft blush and buttery cream to fiery coral, plum, and jewel-toned magenta — gladiolus make a statement wherever they grow.

Height: 2–5 feet (variety dependent)
Bloom time: Mid to late summer
Best for: Cut flowers, back borders, statement plantings
Vase life: 6–10 days

Architectural, expressive, and endlessly cheerful.

How to Grow Gladiola

Warm soil and full sun bring out their best.

🌱 When to Plant

Plant after all danger of frost has passed and soil has warmed to at least 10°C (50°F).
In Alberta, this is typically late May to early June.

For extended bloom, plant in succession every 2 weeks for a longer harvest window.

🌰 Planting

• Plant 4–6 inches deep
• Space 6–8 inches apart
• Pointed side facing up

Planting deeper helps stabilize tall stems.

☀️ Light & Soil

• Full sun (6–8+ hours daily)
• Well-draining soil
• Amend with compost before planting

They do not tolerate soggy soil.

💧 Watering

• Water regularly during active growth
• Keep evenly moist but not waterlogged
• Mulch to retain moisture

🌸 Support

Taller varieties may require staking, especially in windy areas.

✂️ Harvesting

Cut when the bottom 1–2 flowers on the spike begin to open. Remaining buds will continue opening in the vase.

🍂 End of Season (Cold Climates)

In colder regions like Alberta:
• After foliage yellows or first light frost, dig corms
• Allow to dry for several days
• Remove old corm and roots
• Store in a cool (4–10°C), dry place over winter
• Replant the following spring
