Calla Lily vs Lavender Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Calla Lily
Zantedeschia aethiopica
Calla Lilies are rhizomatous herbaceous perennials known for their elegant, trumpet-shaped spathes (often mistaken for petals) that surround a central spadix. While often grown outdoors in gardens, they can be cultivated indoors with proper care. They typically reach a height of 1-3 feet. The plant features large, arrow-shaped, glossy green leaves. People grow them for their striking flowers, which come in various colors, including white, yellow, pink, and purple. They are popular as cut flowers and ornamental plants.
Lavender
Lavandula angustifolia
Lavandula angustifolia, commonly known as English Lavender, is a perennial shrub prized for its fragrant flowers and aromatic foliage. It typically grows to about 2-3 feet tall and wide. Native to the Mediterranean, it thrives in sunny, well-drained conditions. While primarily an outdoor plant, it is sometimes grown indoors, though it requires very bright light to flourish. People grow lavender for its ornamental value, its use in aromatherapy, and its culinary applications. The plant's essential oils are used in perfumes, soaps, and other products.

💡 Pro Tips For Comparing These Plants
Calla Lily Care Tips
Calla Lilies require bright, indirect light and consistently moist soil during the growing season. They need a period of dormancy in the fall and winter with reduced watering. While they can be grown indoors, providing adequate light and humidity can be challenging. Regular fertilization during the growing season is essential for healthy growth and flowering.
- Provide a well-draining potting mix to prevent root rot.
- Allow the top inch of soil to dry out slightly between waterings.
- Fertilize regularly during the growing season with a balanced liquid fertilizer.
- Provide bright, indirect light to encourage flowering.
- Allow the plant to enter dormancy in the fall and winter by reducing watering.
Lavender Care Tips
Lavender is primarily an outdoor plant and requires very bright light to thrive indoors. It is susceptible to root rot if overwatered. Providing adequate drainage and sunlight are crucial for its survival indoors. Expect reduced flowering and overall vigor compared to outdoor plants.
- Ensure excellent drainage to prevent root rot.
- Provide at least 6-8 hours of direct sunlight daily, or supplement with a grow light.
- Avoid overwatering; allow the soil to dry out slightly between waterings.
- Prune regularly to maintain shape and encourage bushier growth.
- Use a low-nitrogen fertilizer sparingly in the spring.

❓ Frequently Asked Questions — Comparing These Plants
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.
Lavender
What are the light requirements for Lavender?
Lavender thrives in full sun, needing at least 6 to 8 hours of direct sunlight daily for optimal growth and flowering. Insufficient light can lead to leggy growth and reduced bloom production. When growing Lavender indoors, place it near a south-facing window where it can receive the most sunlight. If natural light is limited, supplement with grow lights to ensure adequate exposure. Rotate the plant regularly to ensure even light distribution on all sides. Signs of inadequate light include pale leaves, stretched stems, and a lack of flower buds. In hot climates, providing some afternoon shade can prevent scorching of the foliage.
How do I care for Lavender?
Lavender requires full sun, ideally at least 6-8 hours per day. Plant in well-draining soil, as it is susceptible to root rot in overly wet conditions. Water thoroughly when the top inch of soil feels dry, but avoid overwatering. Fertilize sparingly, using a balanced fertilizer diluted to half strength in the spring. Prune after flowering to maintain shape and encourage new growth. Provide good air circulation to prevent fungal diseases. Lavender prefers a slightly alkaline soil pH. Protect from frost in colder climates, either by moving potted plants indoors or providing winter protection outdoors. Regularly check for pests like aphids and treat as needed. Deadhead spent flowers to promote further blooming. Avoid heavy, clay-based soils.
How do I propagate Lavender?
Lavender can be propagated through stem cuttings or division.
