Orobanche ramosa
Also called Branched broomrape, Broomrape
Hemp broomrape is a leafless, chlorophyll-free parasitic annual that grows from roots of other plants, most often crops like tobacco, potato and tomato. It is grown only as a weed or research subject, not as a garden plant, and the key to 'growing' it is that it cannot survive without a host.
Orobanche ramosa is a species of broomrape known by the common names hemp broomrape and branched broomrape. It is native to Eurasia and North Africa, but it is known in many other places as an introduced species and sometimes a noxious weed.
It is a pest in agricultural fields, infesting crops including tobacco, potato, and tomato.
