Answer: The easiest way to propagate a favorite purple cone flower (Echinacea purpurea) is probably by division of an existing plant, but seeds are not terribly difficult -- they will often self seed in the garden. Standard seed starting procedures would apply, using a small pan of barely dampened soilless mix covered with plastic wrap and set in a bright spot out of direct sun. The soil temperature should be about 70 degrees. If the seeds do not germinate within a month, chill them for two to four weeks and then try again.
