Seed Collection: The nutlets mature to shiny black 4-5 weeks after the flower has faded. Only a small percentage viable; these will be plump and swollen. To collect, either take the entire top of the plant or shake it into a paper bag. Seeds can be allowed to dry out before sowing and do not have to be perfectly cleaned. Store in a sealed refrigerated container.
