Orobanche uniflora, commonly known as one-flowered broomrape,[1] cancer root,[2] ghost pipe[3] or naked broomrape, is an annual parasitic herb. It is native to much of North America, where it is a parasitic plant, tapping nutrients from many other species of plants, including those in the Asteraceae and Saxifragaceae families and in the genus Sedum.

It grows to a height of five centimeters, and has short (up to 3 centimeter) scaly leaves. The flowers grow singly on 5–15 centimetres (2.0–5.9 in) stalks and may be up to 3.5 centimetres (1.4 in) long. The corolla is violet to yellow-brown, two-lipped, finely fringed with five similar lobes.
