Chelidonium should be grown outdoors. Seeds should be sown on the surface of flats in either the autumn or early spring. The flats should be set in a shaded location (North facing), and be covered in glass.
Once seedlings appear, they should be transplanted at a spacing of about 30 cm into either a shaded or sunny part of the garden. This should have a moist soil.
Chelidonium plant species self seed, thus they may require weeding to control them in the garden.
The Chelidonium genus consists of only two species.
Chelidonium, especially Chelidonium majus (Greater Celandine), can be interesting additions to gardens, but care must be taken due to its potential toxicity.
Chelidonium majus (Greater Celandine) is often grown for its interesting foliage and yellow flowers.
Chelidonium plants do not have a noticeable fragrance.
Chelidonium prefers shady to partly sunny locations and moist, rich soil.
Currently, Chelidonium majus (Greater Celandine) is considered invasive in several states, as it can spread aggressively.
Chelidonium can be controlled by removing the entire plant, roots included. Also, remove plants before they set seed to prevent spread.
The Chelidonium genus, part of the Papaveraceae family, is native to Europe and western Asia. The most known species, Chelidonium majus, or greater celandine, is a perennial herb recognized for its yellow, poppy-like flowers and lobed, bluish-green leaves.
To cultivate Chelidonium, plant them in partial shade, in well-drained soil. They can be grown from seeds sown in spring or fall, or by root division. Regular watering is necessary, but they can tolerate short periods of drought. However, be aware, as all parts of the plant are toxic if ingested.
