Inside Info /
- Because all the chocolate cosmos trace their heritage back to an original, not self-fertile clone, they do not produce viable seeds. The able grower either uses divisions of another plants tuber or tissue culture to propagate new plants.
- When chocolate cosmos are in the sun, their chocolate aroma heats up too.
