It looks like Firebush bush(Hamelia patens), which is also called Hummingbird bush to me. Despite it's name, it can grow to be a small tree and it's native from Florida South down to Argentina(most all of the tropical Americas). This wasn't growing near Old Peak or Luggard Road in Hong Kong, was it?

BINGO! Pavonia looks exactly like mine. WHEW! Nice to know it's name and now I guess I need to know what to do to corral it. It seems to want to take up too much room. We cut it down to the ground last spring as we'd had a severe ice storm. It came back with a vengeance.

im thinking bleeding heart also .. and its yellowing toward dormancy ... what gal said ,.. put a stick in the ground there.. so you dont plant something over it.. before next spring ... back in my fall bulb planting days.. i cant imagine how many of them i killed thinking.. oh.. there's a nice empty spot.. lol .. ken
