Yes it will come again next year but it is tender advice is cold areas is to lift in autumn allow to dry off and store cool but frost free over winter planting again next spring.

Poor you, our garden is also battered...again , lupins, delphiniums and sweet william lying injured everywhere you look :o( .
You could give your cosmos a light trim to remove broken stems and tidy it up. There's still enough summer left that it might come again...good luck :o)

I guess you've had this afternoon's wind today as well Treeman :) I've moved my pot to somewhere (hopefully) a bit more sheltered. Seems most stalks have been split though :(. Finger's crossed it's not beyond help....
