Any idea what this is?
We moved to a new house in the scottish borders in late summer last year and had a bed filled with these slightly alien looking flowers growing en masse like weeds. The leaves on the plant all became coated with a powdery mildew towards the end of the summer.
Does anyone have any ideas what they are?
I'm a bit of a gardening newbie so my knowledge of plants is still growing so any help is appreciated.
