My DH returned from the Champagne area of France last week and took a picture of this tree thinking I might know what it is...duh.. close up would have been nice. Anyway I told him it may be a long shot but I would ask if anyone on DG might know ?
Hi there! Just stumbled across your question! (I don't get onto DG very often. :-(
Not sure if your question has been answered elsewhere, but it looks very much like a Lagerstroemia Indica (local name "Lilas des Indies"). They grow in profusion round here and I think the pink is nearer the "Lilas" colour than a Judas Tree (Cercis) which is more purple/pink. Also, the flower bunches look more like the "Lilas". Hope this is helpful.
Oh, and in Texas the "Lilas" are called Crape Myrtle I am told!!
You've had your answer on the ID forum, but just adding to agree with Resin. It flowers before the leaves directly on the branches and, flowering in April/May, then it is a Cercis. They certainly grow to that size here. They are used as a street tree in Tarbes, the main town in Hautes Pyrenées. On the other side of the road are Magnolia grandiflora :)
