anything with yellow pompom flowers will do. Albizia julibrissin is the Silk

stems.

I have to say I agree with that Bob, I had a mimosa growing as a mature
tree in my conservatory many years ago. It flowered every Christmas
and as you can imagine, yellow pom-poms everywhere - and I have to
admit to my inexpert knowledge by admitting I have no idea what the
real name was

I think garden centres, this was bought at Notcutts, should give a some
more information when one is purchasing, I cannot remember anying other
the general name on the label. These days I would go to a nursery
where the owners not only sell you a plant, but ensure that you are
informed fully on its history and care before taking it home.
