Introduction to Calla Lilies
The calla lily is not a genuine lily but has a place in the Araceae family. Its genus, Zantedeschia, comprises several species native to southern Africa. Known for their simplicity and grace, calla lilies are popular as ornamental plants in gardens, floral arrangements, and wedding bouquets.
Despite their common name, these flowers are technically arum plants. They thrive in various climates, showcasing a range of colors beyond their iconic white blooms, including shades of pink, purple, orange, yellow, and even near-black.
Botanical Characteristics
Calla lilies are herbaceous perennials with several distinguishing features:
- Flowers and Spathes:
The “flower” is actually a spathe—a modified leaf—enveloping the spadix, a columnar structure containing tiny flowers. The spathe’s vibrant color and smooth texture are what make calla lilies so visually striking. - Foliage:
The plant’s leaves are arrow-shaped and often have unique, spotted patterns. They are typically dark green, complementing the bright spathes. - Height:
Depending on the species and variety, calla lilies grow between 1 and 3 feet tall, making them versatile for garden design and arrangements. - Rhizomes:
Calla lilies grow from rhizomes, underground stems that store nutrients and water, enabling the plant to survive dormant periods.
History and Symbolism
Origins and History
Calla lilies originate from southern Africa, thriving in marshy, wetland environments. The name Zantedeschia honors Italian botanist Giovanni Zantedeschi, while the term “calla” comes from the Greek word kallos, meaning beauty.
European explorers introduced the calla lily to other continents in the 17th and 18th centuries. Since then, it has become a symbol of sophistication and has been widely cultivated in gardens, greenhouses, and nurseries.
Symbolism
Calla lilies carry rich symbolic meanings:
- Purity and Innocence: The white calla lily is a traditional symbol of purity, making it a favorite for weddings and religious ceremonies.
- Rebirth and Resurrection: The flower’s association with Easter and its hardy nature evoke themes of renewal.
- Elegance and Beauty: The plant’s simple yet striking form has made it an enduring symbol of refined beauty.
Different colors of calla lilies convey specific meanings:
- White: Purity and holiness.
- Yellow: Gratitude and joy.
- Pink: Admiration and romance.
- Purple: Royalty and passion.
- Black (deep maroon): Mystery and elegance.
Growing and Caring for Calla Lilies
Ideal Growing Conditions
Calla lilies are relatively low-maintenance plants but require certain conditions to thrive:
- Climate:
- Calla lilies grow best in USDA zones 8–11. In cooler regions, they can be grown as annuals or brought indoors during winter.
- They prefer mild temperatures between 60–75°F (15–24°C).
- Soil:
- Well-draining soil is essential, as calla lilies dislike soggy conditions—correct overwhelming soils with the natural matter for superior waste.
- A somewhat acidic to impartial pH (6.0–7.0) is ideal.
- Light:
- Calla lilies require full sun to partial shade. In hot climates, afternoon shade helps prevent scorching.
- Water:
- These plants thrive in consistently moist soil but should not sit in waterlogged conditions.
- Water regularly during the growing season, but reduce watering during dormancy.
Planting Calla Lilies
- Rhizome Selection:
Choose firm, healthy rhizomes without signs of mold or damage. - Planting Time:
- In warm climates, plant rhizomes in spring after the last frost.
- In cooler regions, start rhizomes indoors 8–10 weeks before transplanting.
- Spacing and Depth:
- Plant rhizomes 3–4 inches deep and 12–18 inches apart.
- Ensure the pointed end faces upward.
- Mulching:
Mulch around the plants to hold soil dampness and control temperature.
Maintenance
- Fertilization:
- Use a balanced fertilizer (10-10-10) every month during the growing season.
- Reduce fertilization as the plant enters dormancy.
- Pruning:
- Deadhead spent flowers to encourage more blooms.

- Overwintering:
- In colder climates, dig up rhizomes in the fall, clean them, and store them in a cool, dry place.
- Replant in spring for the next growing season.
