Pokeweed Seeds: Identification and Propagation

A gardener identified pokeweed 5 years ago and now sees stacked, half-inch diameter discs with papery centers on the stalk, wondering if they're seeds and how to grow them.

Expert Clarification: Pokeweed (Phytolacca americana) seeds are inside the dark purple berries, not in stacked discs on the stalk. The described structures sound like seed capsules of a different plant. You need the exact botanical name (Latin binomial) of your specific pokeweed to research its seed morphology. Search using that name. Harvest seeds from ripe berries, clean them, and sow in fall or stratify for spring planting. Caution: all parts of pokeweed are toxic if ingested improperly.
