Orobanche vallicola is a species of broomrape known by the common name hillside broomrape or valley broom rape. [1]
It is endemic to California and grows in forest openings and woodlands. [2]
Orobanche vallicola is a parasite growing attached to the roots of other plants, generally Sambucus species. The plant produces a thick, hairy, glandular pinkish stem up to about 40 centimeters tall.
As a parasite taking its nutrients from a host plant, it lacks leaves and chlorophyll.
The inflorescence is a cluster or branching array of flowers. Each tubular flower is up to 3 centimeters long, yellowish to pinkish and red-veined in color.
