Pattersons' Curse
 

I had a lovely plant grow by itself in my garden once, and always one to
give plants a chance I gave it plenty of water and fertiliser to help it
along ... and then it flowered! You should see what Patersons Curse will
do with water and fertiliser! We usually see it growing scraggly in
neglected fields! It was huge! And provided much amusement for all my
neighbors. Mind you they didn't recognise the giant growing in my garden
until it flowered either. I kept a very close eye on it and pulled it as
soon as it looked like it had seeds developing.

Least I think that's what it is!
I was driving past a meadow of deep purple (my favourite colour)
anywho I stopped, took a cutting and I am now told it's Patterson's Curse!
I have a HUGE garden so there's plenty of room.
How bad is this delightful flower?
