Greater celandine is a perennial herb with an erect habit, and reaches 30 to 120 cm high. The leaves are pinnate with lobed and wavy-edged margins, 30 cm long. When injured, the plant exudes a yellow to orange latex. The flowers consist of four yellow petals, each about 1 cm long, with two sepals. A double-flowered variety occurs naturally. The flowers appear from late spring to summer in umbelliform cymes of about 4 flowers. The seeds are small and black, borne in a long capsule. Each has an elaiosome, which attracts ants to disperse the seeds (myrmecochory). It is considered an aggressive invasive plant in natural areas (both woods and fields). Control is obtained mainly via pulling or spraying the plant before seed dispersal.
