Greater Celandine vs Indigo Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Greater Celandine
Chelidonium majus
Greater celandine is a herbaceous perennial plant typically growing to a height of 30-120 cm. It features deeply lobed, bluish-green leaves and produces small, yellow flowers in umbel-like clusters from spring to autumn. The plant is characterized by its orange-yellow latex sap, which exudes when stems are broken. It is primarily an outdoor plant, often found in waste places and along roadsides. People sometimes grow it for its purported medicinal properties, though caution is advised due to its toxicity.
Indigo
Indigofera tinctoria
Indigofera tinctoria is a shrubby perennial plant, typically growing to a height of 1-2 meters. It features pinnate leaves with 9-13 leaflets. The plant is primarily cultivated for its leaves, which contain indican, a precursor to indigo dye. While it can be grown as an ornamental plant, its primary purpose is for dye production. It's not naturally suited for indoor environments and requires specific conditions to thrive outside its native habitat. People grow it for its historical and cultural significance as a source of natural blue dye.

❓ Frequently Asked Questions — Comparing These Plants
Greater Celandine
What are the light requirements for Greater Celandine?
Greater Celandine prefers partial shade to full shade, thriving in locations that receive dappled sunlight or filtered light throughout the day. Avoid direct sunlight, especially during the hottest part of the day, as it can scorch the leaves. An east-facing location or a spot under a tree canopy is ideal. Insufficient light can result in leggy growth and reduced flowering. If growing indoors, place the plant near a north-facing window or provide artificial light with a grow light for several hours per day. Monitor the plant for signs of stress, such as pale leaves or sunburn, and adjust the light accordingly.
How do I care for Greater Celandine?
Greater Celandine thrives in partial shade to full shade and prefers moist, well-drained soil. Water regularly, especially during dry periods, but avoid overwatering to prevent root rot. Fertilize sparingly with a balanced liquid fertilizer diluted to half strength, only during the growing season (spring and summer) to encourage blooming. Deadhead spent flowers to promote further blooming and prevent excessive self-seeding. Monitor for pests such as aphids and slugs, and treat accordingly. Prune back any dead or damaged foliage to maintain plant health and appearance. Provide adequate air circulation to prevent fungal diseases. Mulch around the base of the plant to retain moisture and suppress weeds. Repotting is rarely necessary as Greater Celandine prefers to be slightly root-bound.
How do I propagate Greater Celandine?
Greater Celandine can be propagated through division. In early spring or fall, carefully dig up the plant and gently separate the roots into smaller clumps, ensuring each clump has healthy roots and foliage. Replant the divisions in well-draining soil and water thoroughly. Keep the soil consistently moist until new growth appears. Stem cuttings are not a reliable method for propagation. Greater Celandine does not produce keikis. Division is the most effective and straightforward way to propagate this plant, allowing you to expand your collection or share it with others. Ensure the divisions are planted in a location with similar light and soil conditions as the parent plant.
Indigo
What are the light requirements for Indigo?
Indigo plants require bright, indirect light for optimal growth and flowering. Insufficient light can lead to leggy growth and reduced bloom production. A location near an east-facing window is ideal, providing gentle morning light. West-facing windows can work, but be cautious of intense afternoon sun, which can scorch the leaves. South-facing windows may require a sheer curtain to filter the light.
How do I care for Indigo?
Indigo plants thrive in bright, indirect sunlight. Direct sunlight can scorch their leaves. Water thoroughly when the top inch of soil feels dry to the touch, ensuring proper drainage to prevent root rot. Maintain humidity levels between 40-60%. Use a well-draining potting mix, such as a blend of peat moss, perlite, and vermiculite. Fertilize every 2-4 weeks during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength.
How do I propagate Indigo?
Indigo can be propagated through stem cuttings, division, and keikis. For stem cuttings, take a 4-6 inch cutting from a healthy stem, remove the lower leaves, and place it in water or well-draining soil. Keep the cutting moist and in a warm, bright location until roots develop. For division, carefully separate the root ball of a mature plant into smaller sections, ensuring each section has healthy roots and foliage. Repot each section into its own container.
