Knapweed Broomrape along the Roman Road

Anne D-N saw an unusual plant whilst out for a walk along the Roman Road on Monday 3rd June.  This was identified as Knapweed Broomrape (Orobanche elatior), a parasitic plant using Greater Knapweed as its host.

Described as 'a stout upright plant growing up to 75cm high, with a long spike of honey-coloured (usually tinged purple) flowers. Totally lacking chlorophyll, it is brownish throughout'.
