That's an Albizia julibrissin (IIRC) not a mimosa (Acacia)
They're half hardy but can be grown in warmer parts of the south west of
England, the Channel Isles and the Scillies. How it would do as a house
plant, I have no idea. I rather doubt it would flourish though.

Very unlikely. It doesn't even appreciate being kept in a pot for
very long and really needs to get its roots out into the soil. It is
a native of Iran and eastwards through the more arid regions of Asia,
where summers are blisteringly hot and winters cold and dry. It will
grow in the southern counties of England if planted in a very well
drained soil. Full sun is essential if it is to flower and the most
successful plants are those that are backed by a sunny, south facing
wall thereby benefitting from reflected heat by day and radiant heat
at night. Adapted to impoverished soils, this is the one tree that
you do not need to feed or water once established - even during the
hottest and driest of summers. It does not flower as a young small
plant, unlike its more tender, much faster growing cousin - Albizia
lophantha, which is easily flowered as a 12 month old in a 5 litre
pot.
