Growth Stages

1

Planting & Sprouting

2-3 weeks

Rhizome is planted and develops initial shoots and roots

Ensure soil is moist but well-draining. Maintain temperatures between 60-70°F. Plant in spring after frost danger passes.

2

Vegetative Growth

4-6 weeks

Glossy, arrow-shaped green leaves emerge and develop; plant establishes strong foliage

Maintain consistent moisture. Apply balanced fertilizer every 2-3 weeks. Ensure adequate light. Remove any yellowing leaves.

3

Budding & Pre-Flowering

2-3 weeks

Flower buds begin to form within leaf axils; spathes start to develop

Continue regular watering and fertilizing. Switch to higher phosphorus fertilizer to encourage blooming. Maintain humidity around 60-70%.

4

Flowering

8-12 weeks (or longer with proper care)

Deep burgundy spathes with golden-yellow spadix open and display full color; flowers appear continuously

Maintain consistent moisture and humidity. Deadhead spent flowers to encourage continued blooming. Continue fertilizing every 2-3 weeks.

5

Decline & Dormancy

4-8 weeks

Flowering slows as temperatures drop or day length decreases; foliage may yellow

Gradually reduce watering. Stop fertilizing. Cut back foliage to 2 inches once it dies back completely. Store rhizomes in cool, dry conditions over winter in cold climates.

Uses

🍳

Ornamental Use Only

Culinary

Calla lilies are NOT edible and should never be consumed. All parts contain calcium oxalate crystals which cause irritation. They are grown purely for their stunning ornamental flowers. [source]

🏠

Cut Flower Arrangements

Household

Captain Romance's deep burgundy spathes with golden spadix are exceptional for high-end floral arrangements, wedding bouquets, and formal displays. The long stems and dramatic coloring make them a florist favorite. [source]

🎨

Dried Flower Crafts

Craft

Calla lily flowers can be dried and preserved for long-lasting floral arrangements, pressed flower crafts, and decorative displays that retain their striking coloration. [source]

🦋

Pollinator Support

Wildlife

The prominent spadix and nectar production attract pollinators including bees and butterflies, making Captain Romance a valuable addition to gardens supporting beneficial insects. [source]

💊

Traditional Medicine (Non-Edible)

Medicinal

Historically used in some traditional medicine systems for skin conditions (external application only), though modern use is limited due to potential irritation from calcium oxalate crystals. Should be approached with caution. [source]

This is not medical advice. LizPlants is not a medical resource. Always consult a qualified healthcare professional before using plants medicinally.

Harvest Tips

Cut flowers with a sharp knife just above the soil line when the spathe is fully open and colored. Harvest in early morning for longest vase life. Cut flowers typically last 5-7 days in a vase with fresh, cool water. For continuous blooms, remove spent flowers promptly. Calla lilies are excellent as cut flowers and can be dried for floral arrangements.

Fun Facts

  • 🌱 Despite their common name 'Calla Lilies,' these plants are not true lilies—they belong to the Araceae family (arum family) and are more closely related to philodendrons and anthuriums than to lilies.
  • 🌱 The distinctive 'flower' is actually a spathe (modified leaf) surrounding a spadix (a spike of tiny true flowers); the spadix in Captain Romance displays a striking golden color that contrasts dramatically with the deep burgundy spathe.
  • 🌱 Captain Romance is a hybrid cultivar developed through breeding programs to achieve the unique deep burgundy color and golden spadix combination, making it a relatively modern addition to calla lily varieties compared to the species forms.
