Monster Plant

Can anyone identify this plant? My neighbor gave it to me, she had too many of them. She called it her "Monster Plant", since hers are growing quite large. It looks a lot like the Euonymus on my Green Dreaming blog. Maybe a different variety?
Pretty though, and the flowers are crazy-looking.
It's been identified at BBC message board by a nice person named Sara. It's called Leycesteria Formosa (Himalayan Honeysuckle) It will grow to be over 6 ft. tall! I think it may be in the wrong spot!
