Greater Celandine 100 Seeds Chelidonium majus

Chelidonium majus, commonly known as greater celandine, swallowwort, or tetterwort, is a perennial herbaceous plant native to Europe and western Asia and now naturalized in many temperate regions worldwide. It typically grows 30–80 cm tall, forming clumps of softly hairy, branching stems that exude a distinctive bright yellow-orange latex when cut or broken. The leaves are alternate, pinnately lobed, bluish-green above and paler beneath, with a somewhat fleshy texture and an irregular outline that gives the plant a loose, informal appearance. From spring through early summer, Chelidonium majus produces small but cheerful four-petaled yellow flowers borne in loose umbels, followed by slender, elongated seed capsules that split open to release numerous black seeds with white elaiosomes attractive to ants. The plant prefers partial shade and moist, nitrogen-rich soils and is commonly found along roadsides, woodland margins, hedgerows, walls, and disturbed sites. Valued both for its early-season flowers and its ability to thrive in neglected areas, Chelidonium majus is a resilient, easily naturalized species with a long cultural and medicinal history.
