Identify Bamboo Species Please

[ivorhooper]

Hi everyone, I've just moved into my new house in York.
There's a lovely bamboo plant in the garden and I've no idea what it is.

It doesn't have leaves - just small growths at the top of some of the
canes. The canes are bright green and stripy.
It's about four feet high and there's plenty of new canes popping up.
Excuse the rubbish pictures - I had to rotate them to be able to post
them.
Wanting to know how high it will grow and how to manage it.
Thanks in advance!
