Calla vs Harlequin Flower 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.
Harlequin Flower
Tigridia pavonia
Tigridia pavonia, commonly known as the Harlequin Flower or Tiger Flower, is a bulbous perennial prized for its short-lived but spectacular blooms. It produces pleated, sword-shaped leaves from which tall stems arise, bearing several cup-shaped flowers. Each flower lasts only a single day, but successive blooms ensure a display lasting several weeks. The flowers come in a range of colors, including red, orange, yellow, pink, and white, often with contrasting spots or blotches in the center. Primarily an outdoor plant, it is grown for its vibrant summer blooms in gardens and containers. It is not naturally suited to indoor environments.

❓ 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).
Harlequin Flower
What are the light requirements for Harlequin Flower?
Harlequin Flower requires ample sunlight to thrive and produce vibrant blooms. Ideally, it should receive at least 6-8 hours of direct sunlight per day. If growing indoors, place the plant near a south-facing window where it can receive maximum sunlight. Insufficient light can lead to weak growth, leggy stems, and a lack of flowering.
How do I care for Harlequin Flower?
Harlequin Flower thrives in well-drained soil and requires full sun to partial shade. Water regularly during the growing season, keeping the soil consistently moist but not waterlogged. Reduce watering after flowering, allowing the plant to enter dormancy. Fertilize with a balanced fertilizer every 2-4 weeks during the growing season to promote healthy growth and abundant blooms. Deadhead spent flowers to encourage further flowering.
How do I propagate Harlequin Flower?
Harlequin Flower can be propagated through division of the bulbs or by seed. For division, carefully separate the bulbs after flowering, ensuring each section has roots. Replant the bulbs in well-drained soil.
