i was told this is an albizzia julibrissin but thats not right, it aint --- i am in Portsmouth, UK and this thing is in full flower at the beginning of february! i remember it did the same thing last year and lasted best part of 6 weeks -- the owner knows nothing about it.
-- what is it please and
-- how do i propagate it?

thanks, karaman

 

Can you get a close up of the flowers?

 

Sadly your pics are not clear enough.
Have a look at Acacia dealbata.....it flowers in UK now and is hardy in the south.

thanks you peter k and silver surfer, that is it --- acacia dealbata what good news its hardy here in the south, i will be getting one! thanks again.

 

Albeit very pretty, it is an invasive nuisance here, so watch out for seedlings ...

 

Not a problem in UK

Might be hardy in the South of the UK, but not in my garden, most around here were killed a few years ago, so I would say fairly hardy. but not totally.
Acacia pravissima is hardier.
But looks similar in all but leaf.

 

Definitely not hardy in all of the UK and that includes the south coast (I have lost four over the years), depending on the location and cold severity. Given a sheltered sunny spot, even in the north, it can survive but any temperatures below -6/7c will kill a small tree off or at least severely damage it.
From seed it is easy and grows rapidly but most people buy a small tree, some newer cultivars flower younger than the standard Acacia dealbata. Cuttings are not for the beginner they can be difficlult to root (but not impossible).
A pravissima is hardier but I don't think it is as an attractive tree with a lax habit.

 

It's biggest drawback is a horribly invasive root system. Best not planted near a house wall ! Mine didn't take kindly to being pruned, either!
