Blue Morning Glory, what will happen in winter?

Hi Again.

I've also got some blue morning glory growing up a trellis in my garden, it's planted in a plater as the trellis sits on concrete. (Beautiful blue flowers, and I recently realised it has new flowers every day! wonderful).

What happens to this plant as we go into winter? Is it an annual or perennial, does it loose it's leaves, and when does it stop flowering?

So many questions I know, but I am very very grateful for your help.

Thanks for your quick reply, Am learning a whole new language with my attampt at gardening. I'm guessing 'not hardy' means they will die during winter? What/how will this happen (do they just start to drop their leaves) and at what time of the year?
Also where are the seeds and how would I collect them?
I live in Bournemouth so enjoy quite a mild climate.
Many thanks once again.

Hardy refers to the plants ability to survive the winter, esp frosts.
