Broomrape

Broomrape (Orobanche),  Ivy Broomrape (Orobanche hederae) I think, growing along an old mature tree lined wooded corridor through bungalow land. They're a parasitic plant family relying entirely on other plants to stay alive, they don't produce any chlorophyll so need the host to supply nutrients. There are over 200 types of Orobanche and most aren't picky as to their host, although the Ivy Broomrape is, only living on Ivy (as it's name suggests).  Nature never ceases to fill me with wonder.
