propogation

Does anyone know if it is possible to take cuttings of Cosmos Choca Mocha and if so how should I go about it?

Is that the one that smells of chocolate?  I'd like to know that too, mine not started to regrow after winter and concerned that i've actually lost it now.

Yes that's the one and I lost mine over winter so I've bough a new tuber and it's sprouting well. I was hoping it would be possible to propagate in a similar way to dahlias as yet the cuttings I have taken don't look very happy

lift the tubers the way you would dahlias split in the same manner and grow on in greenhouse conditions
