Flowering roadside tree in Shanghai

Just back from a 15 days tour to China.
At Shanghai, there are lots of roadside trees with pinkish red flowers.
The tour guide said these are not local trees, but introduced from
other countries. As we sped along the highways, this is what I could
manage shooting through the window glass.
Wonder if it's appropriate to post non-local trees.

Koelreuteria.

 

Thank you very much indeed.
I found another one I shot in Lingering Garden in Suzhou.
It was taken during sunset. The pinkish red flowers had
a wash of yellow from the setting sun. That's why I missed
this when I posted the thread.

 

The flowers are actually yellow...hence common name Golden rain tree..or Pride of India.


It is the seed capsules that are a beautiful red.

Thanks very much. I just mistook the seed capsules as flowers !

 

Note that trees asked about are not K. paniculata specifically (there are 3 species in the genus).

 

True.
I thought all had inflated seed pods.

Pics below are...... Koelreuteria bipinnata...yellow flowers ..inflated seed capsules.

Thank you for your inputs.
Is there any difference in the shape of the leaves ?
