More commonly known as twisted willow

It would probably have been grafted onto an ordinary willow rootstock. Suckers of the original have taken over from the 'contorta' part that was on top, as they are more vigorous....or you pruned it back too hard and have lost the 'contorta' part.

Whatever is growing in your picture, its definitely not Salix tortuosa - either you were sold the wrong thing, or Volunteer's explanation applies.

Thanks everyone for your comments. If you have time to take a look, I've just posted a pic of the base of the tree which shows all the twisted branches. I've never pruned it so not sure what's gone wrong :-(

my twisted curly willow is more tree like than this..........

Hmmm, I think I've got a Dud, thanks Holly.

Have checked the photo DA and made my comment under there - you're right, it's a dud;-(

Ha ha ha - the story of my life Bamboo.

Well, it has its own charm, regardless;-)

sent you a pm Dawn

Yes Bamboo, it has its own charm in a mutated kind of way, ha ha.

No, I meant it, DA! I bet it gets reflected in the water beneath and it's nice in its own right;-)

;-) It does look OK Bamboo. I was just curious as I've been thinking that it doesnt look like how it should. I've noticed also that some of the smaller branches are kind of flat and square and lined, its very strange. Thanks for all your help today.
