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.
Mexican Orange Blossom

It typically grows to a height and spread of 1-2 meters. The plant is native to Mexico and is primarily grown outdoors as an ornamental shrub in gardens and landscapes. While it can be grown in containers, it thrives best in well-drained soil and full to partial sunlight. People grow it for its attractive appearance, fragrant flowers, and relatively low maintenance requirements.

❓ 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.
Mexican Orange Blossom
What are the light requirements for Mexican Orange Blossom?
Mexican Orange Blossom thrives in bright, indirect light. While it can tolerate some direct morning sun, it’s best to shield it from harsh afternoon sun, which can scorch its leaves. An east-facing window is often ideal, providing gentle morning light.
How do I care for Mexican Orange Blossom?
Mexican Orange Blossom thrives with consistent care. Provide well-draining soil and water thoroughly when the top inch of soil feels dry. Fertilize in spring with a balanced fertilizer to promote healthy growth and abundant blooms. Prune after flowering to maintain shape and encourage bushier growth.
How do I propagate Mexican Orange Blossom?
Mexican Orange Blossom can be propagated through stem cuttings. Take 4-6 inch cuttings from new growth, removing the lower leaves. Dip the cut end in rooting hormone and plant in a well-draining potting mix. Keep the soil moist and provide bright, indirect light.
