USDA Symbol: ORCO4

USDA Native Status: L48 (N)

A fleshy plant with dense spikes, singly or in clusters, of bilaterally symmetrical, dark purple flowers.

The proper classification of this plant remains unclear. It is often considered a subspecies of Prairie Broomrape (Orobanche ludoviciana), a species widespread in the West, and its distinction from Spike Broomrape (O. multiflora) is also debated. All Orobanche species are parasites on the roots of other plants; this species is particularly common on White Bur Sage (Ambrosia dumosa), a shrubby member of the aster family (Asteraceae). It has also become a parasite on tomato crops in southeastern Californias Coachella Valley.
