this is growing out of the wall at the side of house, in shade most of
day if that helps


thanks guys got no idea how it got there, it can't have been planted it's
growing in the morter between the bricks, only bought this house last yr
so it could have been there a few yrs, it seems happy enough growing there
though

This is interesting (from Wikipedia)...
"This plant has an unusual method of propagation. The flower stalk is
initially positively phototropic and moves towards the light—after
fertilization it becomes negatively phototropic and moves away from the
light. This results in seed being pushed into dark crevices of rock walls,
where it is more likely to germinate and where it prefers to grow"

Doesn't explain how it got there in the first place though.
