I love Boronia. Get the right spp (B. megastigma) and your garden will be a perfume delight on a balmy summer evening. Problem is that I have never been able to keep then alive for much over a year. I live on the East coast of Australia while the best Boronias come from Western Australia, and WA plants generally hate growing on the East coast. :-((

Looks to be a legume vine twining around an orchid.

Now that we can see the actual plant, I agree with Euphorbia cotinifolia. The flowers on the euphorb are completely different from that of the smokebush but otherwise they do look similar. so easy to mistake if you are just looking at photos. In fact, the species name of the euphorbia means having leaves that look like cotinus so confusion is rife if not seeing the actual plant :-)

Maria Elena, I don't know if you know it, but if you see the name marnieriana (or another gender-specific version) of the family name Marnier-Lapostelle, it's the same one that produces Grand Marnier. The family has sponsored C&S undertakings (and at least one garden), but I don't know the particulars well.
