Calla vs Polka Dot Plant 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.
Polka Dot Plant
Hypoestes phyllostachya
Hypoestes phyllostachya, commonly known as Polka Dot Plant, is a herbaceous perennial typically grown as an annual or houseplant. It's prized for its vibrant and eye-catching foliage, which features a base color of green, pink, red, or white, heavily speckled with contrasting spots. The plant has an upright, bushy growth habit. While it can flower, the blooms are insignificant; the main attraction is the colorful leaves. It's popular for adding a splash of color to indoor spaces and shaded gardens.

🔬 Botanical Information — Comparing These Plants
Calla
| Scientific Name | Zantedeschia aethiopica |
|---|---|
| Family | Araceae |
| Native To | South Africa |

💧 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.

❓ 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).
Polka Dot Plant
What are the light requirements for Polka Dot Plant?
Polka Dot Plants need bright, indirect light to maintain their vibrant coloration. Insufficient light will cause the colors to fade and the plant to become leggy. An east-facing window is often ideal, providing gentle morning sun. A north-facing window can work if the light is strong enough. Avoid direct sunlight, especially during the hottest part of the day, as it can scorch the leaves. If you don’t have access to sufficient natural light, consider using a grow light to supplement. Rotate the plant regularly to ensure even growth on all sides.
How do I care for Polka Dot Plant?
Polka Dot Plants thrive in bright, indirect light; direct sunlight can scorch their delicate leaves. Water thoroughly when the top inch of soil feels dry to the touch, ensuring good drainage to prevent root rot. Maintain high humidity levels by misting regularly or using a humidifier. The ideal temperature range is between 65-80°F (18-27°C). Fertilize every 2-4 weeks during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Pinch back stems regularly to encourage bushier growth and prevent legginess. Repot in spring when the plant becomes root-bound. Use a well-draining potting mix. Monitor for pests like mealybugs and aphids, and treat promptly if detected.
How do I propagate Polka Dot Plant?
Polka Dot Plants are easily propagated through stem cuttings. Take a 4-6 inch stem cutting just below a node. Remove the lower leaves. Place the cutting in water or directly into moist potting mix. If using water, change it every few days. Roots should develop within 2-3 weeks. Once rooted, plant the cutting in a well-draining potting mix. You can also propagate through division by separating the root ball during repotting. Air layering is another method, but less common. Maintain high humidity during propagation.
