The Chocolate Cosmos ( C. atrosanguinea) is thought to be extinct in 
its Mexican natural habitat, and all the plants of this species 
available in horticuture were propagated by tissue culture from a 
single remaining plant.
 Fertile seed of this species is only obtained by cross pollination of 2 
geneticly separate plants. Since this is not now possible any seed 
from  C. atrosanguinea is unlikely to be "true".
 It looks like you will have to find more plants of this species. It 
is very easy to propagate from cuttings but make sure to cut 
just below the node, as with Dahlias, to ensure that the resulting 
plants do not produce "blind" tubers.
