no its not a tamarix, a friend on fb posted it up, asked what it was, got the answer wisteria, but it clearly wasnt a wisteria! i am botanically educated and the tree in question did not have wisteria shaped flowers or leaves. my 'friend' took exception to me pointing this out and unfreinded me! lol. i wasnt not being rude or disrespectful. but they simply took exception to me disagreeing with them.
so i cannot now copy the picture. its in a private garden and is an unusual speciese.
