Cytinus hypocistis

I saw this colourful and interesting looking plant and wondered what it was. Apparently it is Cytinus hypocistis, a root that has no chlorophyll, external roots, leaves, or stems. It is a perennial that spends most of its life completely inside the root tissue of its host, and the flowers of Cytinus hypocistis are the only component of the parasite that can be seen emerging from the host root, in this case the many rock roses that grow here, during their reproductive season. Its sweet smell above ground is visited by many species of ants that pollinate it.
