Calla vs Calla Lily 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.

💧 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.
Calla Lily
Keep the soil consistently moist during the growing season (spring and summer), but not waterlogged. Allow the top inch of soil to dry out slightly between waterings. Reduce watering in the fall and winter when the plant is dormant. Overwatering can lead to root rot, indicated by yellowing leaves and a musty smell. Underwatering results in drooping leaves and dry soil.

❓ 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).
Calla Lily
What are the light requirements for Calla Lily?
Calla Lilies need bright, indirect light to thrive. Insufficient light can result in fewer blooms and leggy growth. An east-facing window is ideal, providing gentle morning light. If placed in a south or west-facing window, filter the light with a sheer curtain to prevent scorching. Rotate the plant regularly to ensure even light exposure on all sides. Avoid placing Calla Lilies in dark corners or areas with minimal light, as this will negatively impact their growth and flowering. During winter months, when light is limited, consider supplementing with a grow light to ensure adequate light levels.
How do I care for Calla Lily?
Calla Lilies thrive in bright, indirect light; avoid direct sunlight to prevent leaf scorch. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Maintain humidity by misting the plant regularly or using a humidifier. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength to encourage blooming. Reduce watering and stop fertilizing in the fall and winter as the plant enters dormancy. Repot every one to two years in spring, using a well-draining potting mix. Prune away any yellowing or dead leaves to maintain the plant’s health and appearance. Provide a temperature between 60-75°F (15-24°C) for optimal growth.
How do I propagate Calla Lily?
Calla Lilies can be propagated through division, stem cuttings, and keiki (small plantlets). For division, carefully separate rhizomes when repotting, ensuring each section has roots and at least one eye. Plant each division in its own pot with well-draining soil. For stem cuttings, take a cutting from a healthy stem and place it in water until roots develop, then plant in soil. Keiki can be removed when they have developed roots and planted separately. Maintain humidity and provide bright, indirect light for successful propagation. Ensure proper drainage to prevent rot.
