Chelidonium majus, commonly known as Greater Celandine or Swallow Wort, is a captivating herbaceous perennial/biennial that brings a splash of sunshine to your landscape with its vibrant yellow blooms from May through August. Part of the poppy family, this plant thrives in various soil types, preferring rich loams and moist, well-drained conditions, making it a versatile addition to your garden. With a typical height of 1 to 2 feet and a spread of up to 1 foot, it forms attractive clumps of showy 4-petaled yellow flowers on brittle, hairy stems with lobed, gray-green leaves. It's best suited for part to full shade but can tolerate full sun in cooler climates. Known for its aggressive self-seeding habit, Greater Celandine can naturalize swiftly, offering a bright, natural aesthetic to woodland or wild garden settings where spreading is embraced. However, due to its invasive nature, caution is advised as it can become weedy and difficult to control. Its sap is irritating and toxic if ingested, adding a layer of intrigue to this storied plant with historical medicinal uses, famously once thought to remove warts. Though a noxious weed in certain US regions, its charming blossoms and historical lore can make it a noteworthy, albeit carefully managed, garden inhabitant.
