Did You Know?
1. Calla lilies are not truly lilies! Despite their name, they are actually a part of the Araceae family, which includes plants such as peace lilies and philodendrons.
2. In ancient Greek mythology, calla lilies were associated with the goddess Hera. It was believed that these flowers sprang from the milk of Hera, symbolizing purity and fertility.
3. Calla lilies are native to Southern Africa, particularly Swaziland and South Africa. They thrive in wetlands and are often found near streams and ponds.
4. While calla lilies are usually white, they can actually come in various colors including shades of yellow, orange, pink, and even dark purple. These vibrant hues are popular in bridal bouquets and floral arrangements.
5. Calla lilies have a unique property where they are able to naturally purify water. Due to their ability to absorb toxins, some species of calla lilies are used in the process of wastewater treatment, helping to clean and filter water sources.
Propagating Calla Lilies From Rhizomes Or Seeds
Calla lilies can be propagated through two methods: by cutting dormant rhizomes or by planting seeds. When propagating through cutting rhizomes, it is essential to make sure that each section has a visible bud. These sections should be planted in containers with multi-purpose compost, preferably indoors.
Provide sparing moisture until shoots start to emerge. Once this happens, water the plants regularly until they are well-established. At this point, they can be planted outdoors.
Alternatively, propagating calla lilies from seeds involves collecting them in the fall and storing them over winter. In spring, sow the seeds in pots filled with seed compost. To facilitate germination, maintain a consistent temperature of around 70°F (21°C). Expect seedlings to emerge after a few weeks.
Troubleshooting Common Issues With Calla Lilies
While calla lilies are usually trouble-free, there are a few pests and diseases that may affect them. These may include:
- Slugs

- Rot
It is crucial to monitor your plants closely and take appropriate action if any of these issues arise. This could involve using organic pesticides or insecticidal soaps to combat pests or addressing overwatering for rot prevention.
Calla lilies may also fail to bloom due to various reasons such as:
- Excess nitrogen in the soil
- Inadequate moisture
- Excessive shade
- Insufficient dormancy periods
- Early removal of foliage
- Deficient rhizomes
- Incorrect planting methods
To encourage optimal blooming, ensure the planting conditions are appropriate for calla lilies. This includes providing:
- Well-drained soil

- Warm temperatures
“It is important to be aware of the potential pests and diseases that can affect calla lilies. By monitoring your plants closely and creating suitable growing conditions, you can help prevent these problems and ensure beautiful blooms.”
Growing Calla Lilies In The Right Conditions For Perennial Growth
Calla lilies are perennial plants that can come back year after year when provided with the right conditions. To ensure their longevity, follow these tips:
- Soil: Use well-drained soil to prevent waterlogging, which can lead to root rot.
- Watering: Keep the soil moist but avoid overwatering. Regular watering is crucial for the lilies’ growth.
- Sunlight: Provide partial shade to full sun exposure. Calla lilies thrive in bright, indirect light.
In colder climates (below USDA hardiness zone 8), it’s essential to protect calla lilies from frost damage. Here’s what you can do:
- Winter storage: In colder regions, it’s recommended to store calla lilies indoors during the winter.
- USDA hardiness zones: In zones 8-10, calla lilies can withstand winter temperatures and remain in the ground or outdoor containers.
- Foliage trimming: At the end of the growing season, remember to trim back the foliage.
Calla lilies are tropical flowering plants originally from Africa. They can be grown in various settings, including gardens, containers, and indoor spaces. Their vibrant flowers come in different colors, and each hue carries a unique meaning. Here’s a summary of their versatility:
- USDA hardiness zones 8-10: Calla lilies can be grown outdoors year-round.
- Lower zones: In colder regions, they can be grown as annuals or be protected from the cold.
- Containers: Growing calla lilies in containers offers flexibility, especially for those in colder climates, as they can be moved indoors during winter months.
Tips For Prolonging The Life Of Potted And Cut Calla Lilies
If you choose to grow calla lilies in pots, they can last for several weeks to a few months in suitable conditions. Ensure the container has adequate drainage and use a well-draining potting mix.
For cut calla lilies, you can enjoy their beauty in a vase for up to two weeks with the right care. Place the stems in fresh water and remove any foliage that may be submerged. Regularly change the water to prevent the buildup of bacteria. Additionally, cutting a small portion off the bottom of the stems every few days can help with water uptake and prolong the life of the blooms.
Care And Cultivation Instructions For Calla Lilies
To care for calla lilies, consider the following points:
-
Sunlight: The time it takes for blooms to appear depends on the amount of sunlight received by the plants. Ensure they receive partial shade to full sun exposure.
-
Soil: Calla lilies thrive in slightly soggy soil but can rot if there is excessive moisture. Ensure the soil is moist but not waterlogged.
-
Watering: Place the container in a shallow saucer filled with water, keeping the water level below the pot’s drainage holes. Refill the saucer when the water runs dry. When watering calla lilies in the ground, ensure the soil is moist but not waterlogged.
-
Fertilization: For active growth, fertilize the calla lily with a balanced houseplant or all-bloom fertilizer monthly. However, stop fertilizing once the blooms have faded and allow the plant to “rest.”
-
Pruning: Remove spent blossoms using sharp, clean shears. Additionally, prune any dead or yellowing leaves as needed to promote overall plant health.
-
Repotting: Repotting may be necessary 1-2 times during a single growing season, depending on the rate of growth. When repotting, ensure the new pot has good drainage and use fresh potting mix.
-
Toxicity: Calla lilies are considered toxic to cats, dogs, and humans. Take necessary precautions if you have pets or small children around these plants.
- Ensure proper sunlight exposure
- Avoid excessive moisture in soil
- Water by using a shallow saucer
- Fertilize monthly (except after blooms fade)
- Prune spent blossoms and yellowing leaves
- Repot as needed with good drainage
- Be aware of toxicity to cats, dogs, and humans
