The best time to collect seeds from Prairie Smoke (Geum triflorum) is typically late spring to early summer, depending on your local climate — usually from late May to early July in much of the Midwest.

Signs the seeds are ready:

• After blooming, the flowers form distinctive feathery seed heads (resembling pinkish or silvery smoke).

• Wait until the feathery styles begin to dry and fluff out — they should look wispy and start to detach easily when tugged.

• Inside the base of the plume, you'll find the actual seeds (small, dark, and hard).

Tips for successful collection:

• Collect on a dry day to prevent mold.

• Snip the seed heads when the plume is fluffy but not entirely dispersed by wind.

• Store in a paper bag or breathable container until fully dry before cleaning and storing the seeds.

Optional stratification:

Prairie Smoke seeds benefit from cold stratification (simulating winter conditions). Chill them in moist sand or paper towel in the fridge for about 60 to 90 days before sowing to improve germination.
