Often cultivated, this plant is found west of our area (Kentucky, Tennessee). Be careful if you plant this flower in your garden, as it spreads rapidly. The flowers have four yellow petals about an inch long. The flower buds are covered with two hairy sepals, and the fruit is ovoid and bristly hairy. Broken parts of the plant exude a yellow juice. The scientific name, from the Greek stylos, style, and phero, bearing, refers to the fact that the style of the flower remains attached to the tip of the fruit after the flower has withered. A true poppy, it belongs to the Poppy family ( Papaveraceae).

You can often find a similar plant growing along roadsides and other disturbed areas. It was introduced from Europe. This is the Celandine (Chelidonium majus). It differs from the Celandine Poppy in having smaller flowers and smooth fruits which do not retain the styles.
