Pre-treatment: Mix the seeds with an equal amount of either perlite or vermiculite. Put mixture into a Ziploc-style bag or Rubbermaid-style container. Seal and store 1 month in a cool dry place (refrigerator or cold garage). Cold store until planted (up to 3 years).
Establishment: The plant blooms from July to September. The seed is an achene with pappus and is harvested in October. The seed is very small and cutting off the entire plant head saves time in collection. The plant prefers moist or wet low ground, thickets and open woods. It flowers most and seeds ripen best in full sunlight. It can reach a height of up to 5'. It has light purple flowers in terminal clusters.
