This bush is perfuming my whole front yard, and part of the house as well, now that I can have some windows open. I just want to stick my head into and inhale, but there are plenty of bees with the same idea.
It really does smell a lot like orangeblossom, but not quite as pungent. I remember smelling oranges in bloom in Florida, but out in the country, it was frequently mixed with burning garbage. Not a good combination!
