About this weed
This unusual brown weed is a parasitic plant that can grow to 50 cm’s but usually is much smaller and produces pinkish-brown flowers in winter and spring before dying back over summer. It was originally a native of Europe. Note – this species is the only one from the Genus Orobanche not a Declared Pest in Western Australia.
Description
This easily recognised erect, parasitic plant has a translucent pinky brown stem that is sticky to touch. Lesser Broomrape grows from a bulb-like structure underground from which roots penetrate their host. It emerges in winter and produces the brownish flowers in winter and spring.
