What type of tree?

Hi

I was wondering if you would be able to help me identify what type of tree this is.

I have seen them before with a single stem/trunk but all four of ours are multi-stemmed. At this time of year (on the Highveld) they become heavily laden with blooms, and sometimes the boughs bend right down to the ground and occasionally break off.

I would also like to know if it is possible to grow more of these trees from cuttings, and if so how is it done.

Thank you.

John
