Cold/Moist Storage - 60 days
Germination - Best results - We collect our seed and plant it outside in a well-drained flat, protected from heavy rain. Old windows work great! If it is a warm, dry winter, flats will need to be occasionally watered.
Viable seed - Start with three or more mature plants. Many times flowers develop in the first season. Collect seed late in the fall once they are brown. Only collect seed when it is dry, never after it has rained. Store in a paper bag, let seed sit for a few weeks, move to a container with a lid. I save different sized containers throughout the year.
Collect only what you need - Leaving extra on the plant provides food for birds and other animals. An extra bonus, in the spring you will be rewarded with a generous supply of young New York Ironweed seedlings.
