Flowers gone crazy

This morning we walked to church through Pignatelli Park in Zaragoza. It's been a horrible windy spring day, but I was very struck by some flowers coming out of the garden of a Modernist building next to the Italian Church.

They look like escapes from a fairy story (I saw Beauty and the Beast last week) According to the park web page 

they are "thornless rose" I looked in Wikipedia and the say :Rosa banksiae, common names Lady Banks' rose, or just Banks' rose. 

Really pretty!
