Spanish bluebells.

My only excuse is that at the time I was lead to believe they were
native ones, but now I know better having seen the real deal in flower
along Cornish lanes.

I was once rash enough to introduce orange hawkweed. It's one of my
favourite wild flowers, and of a colour you don't see too often in
British natives; and in the wild it's far from virulent. In the garden,
however, it seemed intent on invading Poland, increasing by seed and a
network of runners. Curiously, its quarters were not at all luxurious:
I'd put it in a problem patch of poor soil and broken shale.
