The flowers look like a clerodendron, but the leaves less so. Which isn't really much help I'm afraid... I used to have one, but it didn't flower until summer.
PS - I recall my clerodendron had a distinctive smell.

Knowledge is knowing that a tomato is a fruit. Wisdom is not putting it in a fruit salad.
Can you tell us a bit more about it please. Where is it growing? Are its stems square, they look a bit like it. Is it a shrub or a herbaceous perennial? Are you in the UK?
