Yes! Laburnum has a very strong fragrance. I have had many problems with it, since I am allergic to peanuts and all trees in the fabiciae family. I have had to move out of apartments in the last because there was one nearby.

I currently moved in to an apt. that had a Laburnum straight outside the bedroom window, but the landlord agreed to cut it down. Still, there is that strange smell in the apt., specially in the bedroom.

Did you have any luck getting rid of the odor? It makes me very dizzy and if I can't find a solution we will have to move out again.
