Chelidonii Herba

What is the plant

Greater celandine is a perennial herb with an erect habit, and reaches 30–120 cm (12–47 in) high. The blue-green leaves are pinnate with lobed and wavy margins, up to 30 cm (12 in) long. When injured, the plant exudes a yellow to orange latex, or sap. The flowers consist of four yellow petals, each about 18 mm (0.71 in) long, with two sepals. A double-flowered variety occurs naturally. The flowers appear from late spring to summer, May to September (in UK), in umbelliform cymes of about 4 flowers. The seeds are small and black, borne in a long, cylindrical capsule. Each has an elaiosome, which attracts ants to disperse the seeds (myrmecochory)

How to Care for the Plant

Water
Water regularly in the first weeks. Try to avoid watering on sunny afternoons to minimize the amount of moisture lost to evaporation. If your plant is in a pot, check the top soil in the pot either by looking at it or touching it with your finger. In any case, if it hasn’t rained in a month, water !
Pruning
Deadhead to prevent self-seeding.
Fertilizer
Greater celandine loves nutrient-rich soils and has an increased nutrient requirement. Above all, nitrogen consumes the herb in considerable amount. Inasmuch as the soil in which the plant grows is nutrient-rich, in most cases it is not necessary to re-fertilize. In the following year you should then treat the soil in the spring with a nitrogen-stressed fertilizer. Good compost or long-term organic fertilizers such as pellets are particularly suitable here. In nutrient-poor soils, it is often necessary to re-fertilize at the beginning of the summer. The same applies to potted cultures. Here, about every 6 weeks small fertilizer should be administered.
