My daughter sowed some banana seeds about 12 months ago. One seed
germinated and is now 6ft tall and visibly growing in our conservatory by
the day! The conservatory roof is 12ft max.
How high do they grow (gulp)

Depends on how big of a pot they are put in. The bigger the pot, the bigger
the plant. Ours have gotten to about 6 ft, but they were put out side only
during the summer. As the leaves died, new ones came back.

Do they survive outside? - We live in Leicestershire

If they have to stay indoors can they be "pruned " and if so will they
grow
again (as was claimed at the NEC Gardeners World Exhibition)?

Yes they will come back. You put them outside during the summer (if the
wind doesn't blow too strong), dig them up in the fall, shake most of the
dirt off of the roots, put he root ball into a plastic or paper bag, cut off
all the leaves, and store it in a cool building that wont let it freeze, and
replant in the spring. We lost two out of 6 one year, so now we just pot
them and bring them inside.
