Introduction

Calla lilies (Zantedeschia spp.) are known for their exquisite trumpet-shaped blooms that grace gardens and add a touch of sophistication to any room. While typically propagated through rhizomes or bulbs, calla lily seeds are also an available option for gardeners seeking to establish new plants. This comprehensive guide will provide you with all the essential information you need to select, grow, and appreciate these elegant flowers from seeds.

Selecting Calla Lily Seeds

Quality Matters

As with any plant, choosing high-quality seeds is crucial for successful germination and growth. Look for seeds that are fresh, plump, and free from disease or damage. Reputable seed suppliers are more likely to provide viable seeds.

Species and Varieties

Several species and varieties of calla lilies produce seeds. Choose the ones that suit your climate, growing conditions, and desired flower characteristics. Some popular options include:

• Z. aethiopica (White calla lily): Hardy and produces pure white blooms.
• Z. elliottiana (Yellow calla lily): Produces bright yellow blooms.
• Z. rehmannii (Pink calla lily): Bears pink to purple-tinged flowers.

Hybrids

Hybrids offer a wider range of colors and forms to choose from. However, they may not come true to their parent plants and may require more specific growing conditions.

Sowing Calla Lily Seeds

Sowing Time

The ideal time to sow calla lily seeds is in early spring, indoors, 8-10 weeks before the last expected frost.

Soil Conditions

Prepare a seed-starting mix that is well-draining and pH-neutral. A mixture of peat moss, perlite, and vermiculite is suitable.

Planting Depth

Sow seeds on the surface of the soil and gently press them in. Do not cover them with soil, as they need light to germinate.

Temperature and Humidity

Calla lily seeds require warm temperatures between 60-70°F (15-21°C) to germinate. Maintain high humidity by placing a clear plastic cover over the seed tray.

Early Care and Maintenance

Watering

Water the seeds vorsichtig, keeping the soil moist but not waterlogged. Avoid letting the soil dry out.

Light

Provide the seedlings with bright, indirect light. Direct sunlight can scorch the delicate plants.

Thinning

Once the seedlings have developed their first set of true leaves, thin them out to the strongest plant every 2-3 inches.

Transplanting

When the seedlings have several sets of leaves and are large enough to handle, transplant them into individual pots or cells. Gradually accustom them to outdoor conditions by hardening them off over a week.

Growing Calla Lilies Outdoors

Plant Location

Choose a location with well-drained soil, partial shade to full sun, and protection from strong winds.

Plant Spacing

Space the plants 12-18 inches apart to allow for proper growth and air circulation.

Watering

Water the plants deeply and regularly, especially during hot, dry weather. Allow the top inch of soil to dry out before watering again.

Fertilizing

Fertilize the plants monthly with a balanced fertilizer during the growing season.

Enjoy Your Calla Lilies

Cut Flowers

Calla lilies make striking cut flowers. Harvest them when the lower flowers on the stem are fully open and the upper ones are still tightly closed. Remove the yellow pollen-producing spadix from the center of the bloom to prevent staining.

Overwintering

In colder climates, calla lilies can be overwintered in a dormant state. Allow the foliage to die back and reduce watering gradually.

• Hardiness Zones 7-11: Store the rhizomes in a cool, dry place with temperatures between 45-50°F (7-10°C).
• Hardiness Zones 5-6: Mulch the plants heavily to protect them from the elements.

Conclusion

Growing calla lilies from seeds is a rewarding experience that can provide you with an abundance of beautiful blooms. By following the tips and techniques outlined in this guide, you can successfully cultivate these elegant plants and enjoy their graceful presence in your garden or home.
