Orobanche, commonly known as broomrape, is a genus of almost 200 species of small parasitic herbaceous plants, mostly native to the temperate Northern Hemisphere.
They are best recognized by the yellow- to straw-coloured stems completely lacking chlorophyll, bearing yellow, white, or blue snapdragon-like flowers.
Broomrape seeds remain dormant in the soil, often for many years, until stimulated to germinate by certain compounds produced by living plant roots.
Branched broomrape Orobanche ramosa, native to central and southwestern Europe but widely naturalised elsewhere, is considered a major threat to crops in some areas.
[6] The generic name Orobanche comes from the Greek ὀροβάγχη (orobánkhē), from ὄροβος (órobos "bitter vetch") + ἄγχω (ánkhō (I) "strangle").
