Cordyline Australis ‘Red Star’ – Growth & Protection

Question

Afternoon, I have a Cordyline australis ‘Red Star’ which is currently happy and healthy in a pot (2 feet high).  I would like to keep it in the pot permanently.  Is this possible without any harm coming to the plant and if so, high tall can it grown in the pot?  Also, I have just tied the leaves together to protect it from the cold frosty weather.  Is this enough to protect it or do I need to cover it completely?   Thank you for any assistance.

If winter temperatures get below freezing, I would bring it in for the winter. Here is more:
