Ranunculus (Corms)

Petal upon petal, like silk folded into a flower.

Ranunculus are beloved for their densely layered, paper-thin petals that form lush, rose-like blooms. Each flower opens slowly, revealing concentric rings of colour — from soft blush and buttercream to coral, wine, and bold jewel tones.

They carry an old-world elegance yet feel fresh and modern in bouquets. Whether grown for cutting or admired in the garden, ranunculus bring refined beauty to the cool seasons.

Height: 12–24 inches

A florist’s favourite and a gardener’s treasure.

How to Grow Ranunculus

Cool roots. Bright light. Patience rewarded.

🌱 When to Plant

Ranunculus prefer cool growing conditions.

In colder climates (like Alberta):
• Plant outdoors in early spring once soil is workable
• Or start in a cool greenhouse for earlier blooms

In mild climates, they can be planted in fall for spring flowering.

🌰 Preparing the Corms

Ranunculus corms resemble little dried octopus feet.
• Soak in room-temperature water for 3–4 hours before planting
• Do not oversoak
• For best results, pre-sprout in moist soil in a cool space (optional but helpful)

🌿 Planting

• Plant 1–2 inches deep
• Claws facing downward
• Space 4–6 inches apart

☀️ Light & Soil

• Full sun preferred
• Well-draining, rich soil
• Amend with compost before planting

Drainage is essential — they do not tolerate soggy soil.

💧 Watering

• Keep evenly moist during growth
• Avoid waterlogging
• Reduce watering as foliage yellows after flowering

🌸 Blooming

Expect blooms approximately 90 days after planting. Cooler growing temperatures produce stronger stems and more vibrant flowers.

🧺 After Flowering

• Allow foliage to die back naturally
• In cold climates, lift and store corms in a cool, dry place
• In very well-drained beds, some gardeners experiment with overwintering, though success varies

Why Grow Ranunculus?

• Exceptional cut flower quality
• Long vase life
• Wide colour range
• High bloom count per corm

They feel like something from a Dutch still-life painting — luminous, layered, and unforgettable.
