I couldn't say for sure Lin, there looks to be a certain plant doing the rounds in the US! The naming of it is suspect.
The photo provided by bamira (Stefan) was taken at the botanical gardens in Berlin so I would take that as a sound ID. The leaves do look narrower. The other photo posted by him I came across on google, but I'm not aware of the credentials of the people who took the photo so take that with a pinch of salt.
