Calla vs Pomegranate Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Calla
Zantedeschia aethiopica
Zantedeschia aethiopica, commonly known as Calla Lily, is a rhizomatous herbaceous perennial prized for its elegant, trumpet-shaped spathes (modified leaves) that surround a central spadix. While often called a lily, it is not a true lily. It grows from rhizomes, producing large, arrow-shaped, glossy green leaves. It is primarily an outdoor plant, thriving in moist conditions. People grow it for its striking flowers, often used in bouquets and floral arrangements. It can be grown indoors, but requires specific conditions to thrive and may not flower as readily as outdoors.
Pomegranate
Punica granatum
Punica granatum, the pomegranate, is a deciduous shrub or small tree typically grown outdoors. It features glossy, oblong leaves and vibrant red, orange, or white flowers. The fruit is a round, leathery berry filled with juicy, seed-filled arils. Pomegranates are cultivated for their ornamental value, edible fruit, and purported health benefits. While it can be grown in a container, it requires specific conditions to thrive and fruit indoors, making it primarily an outdoor plant.

💧 Watering Needs
Calla
Keep the soil consistently moist, especially during the growing season. Water thoroughly when the top inch of soil feels dry. Reduce watering in the dormant period. Overwatering can lead to rhizome rot, indicated by yellowing leaves and a foul odor. Underwatering results in wilting and browning leaf tips.
Pomegranate
Water deeply when the top inch of soil is dry. Avoid overwatering, which can lead to root rot. Reduce watering during dormancy in winter. Signs of underwatering include wilting leaves and dry soil. Overwatering signs include yellowing leaves and soggy soil.

💡 Pro Tips For Comparing These Plants
Calla Care Tips
Calla Lilies require bright light and consistent moisture. They can be grown indoors, but may not flower as readily as outdoors. Ensure good drainage to prevent rhizome rot. Toxicity to pets is a significant concern. Requires a dormant period in winter.
- Provide a dormant period in winter by reducing watering and keeping the plant in a cool location.
- Ensure good drainage to prevent rhizome rot.
- Fertilize regularly during the growing season to promote flowering.
- Monitor for pests and diseases and treat promptly.
- Provide bright, indirect light for optimal growth and flowering.
Pomegranate Care Tips
Pomegranates are best suited for outdoor cultivation. Indoor growing is challenging due to high light requirements and the need for a dormant period. They require full sun, well-draining soil, and careful watering. Fruiting indoors is unlikely without significant effort.
- Provide at least 6 hours of direct sunlight daily for optimal growth and fruiting.
- Water deeply but infrequently, allowing the soil to dry out slightly between waterings.
- Fertilize regularly during the growing season with a balanced fertilizer.
- Prune annually to maintain shape and remove dead or crossing branches.
- Protect from frost in colder climates by wrapping the trunk or moving the plant indoors (if in a container).

❓ Frequently Asked Questions — Comparing These Plants
Calla
What are the light requirements for Calla?
Calla lilies thrive in bright, indirect light. Direct sunlight can scorch their leaves, so avoid placing them in south-facing windows without some form of shading. An east- or west-facing window is ideal, providing ample light without the intensity of direct sun. If you notice the leaves becoming pale or the plant failing to bloom, it may not be receiving enough light. In such cases, consider supplementing with artificial grow lights. During the darker winter months, supplemental lighting is particularly beneficial to maintain healthy growth and encourage future blooms. Ensure the light is diffused to prevent leaf burn. Regular rotation of the plant ensures all sides receive adequate light, preventing uneven growth.
How do I care for Calla?
Calla lilies require bright, indirect light for optimal growth and blooming. Water thoroughly when the top inch of soil feels dry, ensuring proper drainage to prevent root rot. During the growing season (spring and summer), fertilize every 2-4 weeks with a balanced liquid fertilizer diluted to half strength to encourage flowering. Reduce watering and fertilization during the dormant period in fall and winter. Maintain a humidity level of 50-60%. Repot annually in spring using well-draining potting mix. Remove spent flowers to encourage more blooms. Monitor for pests like aphids and spider mites, and treat promptly if detected. Provide support for taller varieties to prevent them from bending. Rotate the plant regularly to ensure even growth and prevent leaning towards the light source. Protect from frost and freezing temperatures.
How do I propagate Calla?
Calla lilies can be propagated by division, stem cuttings (though less common), and keiki (small plantlets that sometimes form on the plant).
Pomegranate
What are the light requirements for Pomegranate?
Pomegranates are sun-loving plants and require ample light to thrive indoors. Aim for at least 6 hours of direct sunlight per day. A south-facing window is ideal. If direct sunlight isn’t available, supplement with grow lights. Insufficient light can lead to leggy growth, reduced flowering, and poor fruit production. Rotate the plant regularly to ensure even light exposure on all sides. During the winter months, when daylight hours are shorter, consider increasing the duration of grow light exposure. Monitor the plant for signs of light stress, such as pale leaves or stunted growth, and adjust the light accordingly. Supplementing with artificial lighting is almost always necessary for indoor growing.
How do I care for Pomegranate?
Pomegranate trees thrive with consistent care. Provide bright, direct sunlight for at least 6 hours daily. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Maintain a pot size appropriate for the plant’s size, repotting every 2-3 years into a slightly larger container with well-draining potting mix. Fertilize monthly during the growing season (spring-summer) with a balanced liquid fertilizer diluted to half strength. Prune in late winter or early spring to maintain shape, remove dead or crossing branches, and encourage fruiting. Provide stable conditions, avoiding sudden temperature changes or drafts. Monitor for pests like spider mites or aphids and treat promptly. A balanced approach to light, water, and nutrients will ensure a healthy and productive Pomegranate tree.
How do I propagate Pomegranate?
Pomegranates can be propagated through stem cuttings or air layering.
