About

Narthecium americanum is a species of flowering plant in the Nartheciaceae known by the common names yellow asphodel and bog asphodel. It is native to New Jersey in the United States. It is now apparently limited to that state, having likely been extirpated from Delaware, North Carolina, and South Carolina.

This rhizomatous perennial herb produces an erect stem 25 to 45 centimeters tall. It has narrow linear leaves up to 20 centimeters long by just a few millimeters wide around the base of the stem. Smaller leaves occur higher on the stem. The inflorescence is a dense raceme of yellow flowers that bloom in June and July. The fruit is a papery, beaked capsule a centimeter long or slightly longer. It contains yellow seeds.
