Most other broomrapes bear several flowers along a stem. Clustered Broomrape also has single-flowered stalks, but typically more stalks per underground stem and a more distinctly two-lipped flower.
Each hairy stalk ends in a single white to pale lilac flower.
The tubular flower opens into five spreading lobes, often with yellow hairs in the throat.
Green leaves are absent; the plant obtains nutrients from host roots. Pair close views with a photograph of the whole plant.
