Orobanche minor is a perennial holoparasite with no chlorophyll that attaches to the roots of clovers and other pea and daisy family plants to take its food. It is grown only by accident as a weed, and the key to controlling it is managing its host plants rather than the broomrape itself.

Family
Orobanchaceae (Orobanch family)
Light
Full sun, Part shade
Water
It gets water from its host plant's roots, so it needs no watering of its own.
Soil
Grows in moist sandy, loamy or clay soils that are acid, neutral or basic.
Native range
Europe to N. Iraq, Macaronesia to Arabian Pen. and S. Trop. Africa
Climate
temperate

About

Orobanche minor, the hellroot, common broomrape, lesser broomrape, small broomrape, broomrape minor or clover broomrape, is a holoparasitic flowering plant belonging to the family Orobanchaceae. It is one of about 150 non-photosynthetic plants in the genus Orobanche that parasitize autotrophic plants. It is a federally listed noxious weed in the United States.

Where it grows

Common broomrape is one of the most widespread species. It is native to Southern Europe, but has been widely introduced elsewhere. It has been observed on clovers in the United States and flatweed in Canada. In New Zealand it is the only species of the genus present where it is regarded as an agricultural pest. In the United Kingdom it is widely recorded in southern England, less common in Wales, rarely recorded in lowland Scotland and absent from the Highlands and outer islands.
