Purple Orobanche? (1 Viewer)

Tiraya

San Diego CA
United Kingdom
Anyone know this one? I thought I had never seen an Orobanche that wasn't brown or yellow until I found this filed under unidentified... (Or maybe it isn't Orobanche)

It was along the coastline of Normandy, France, wetland/meadow area.

Nice...one reason I love France, so many common species that are rare or uncommon in the UK.

That is indeed a suitable common name for the species...I've found a few matching pictures though none say what the scientific name is -- there is a Orobanche purpurea but with the common name "Yarrow broomrape" instead?

Interesting...I wonder why a plant that relies on such a common partner species has become so rare in the first place.
 
Yarrow Broomrape, like many other broomrapes, must need a very specific habitat... In the Netherlands, it requires calcium-rich, nutrient-poor, sandy soil (found in 43 25-km² squares, all but 9 on dune sand), unlike yarrow which will grow on any kind of soil (1648 25-km² squares). It has disappeared from inland sites, where too many fertilisers have destroyed its habitat.
