Orobanche vallicola
Also called Valley Broomrape
Hillside broomrape is a leafless, non-photosynthetic parasitic plant that grows on the roots of host plants, mainly elderberry (Sambucus). It cannot be grown like a normal garden plant without its host, so success depends on a living host nearby.
Orobanche vallicola is a species of broomrape known by the common name hillside broomrape or valley broom rape.
It is endemic to California and grows in forest openings and woodlands.
