Daisy Fleabane (Erigeron strigosus)

 

Seed Collection Time:

Late summer to early fall — typically August through October, depending on bloom time and region.

 

Signs seeds are ready:

  • After flowering, the plant forms small, fluffy seed heads (similar to tiny dandelions).

  • As the heads mature, they become white and puffy, and seeds begin to detach easily with wind or touch.

  • Seeds are tiny, brown to tan, each attached to a tuft of fine hairs (pappus) for wind dispersal.

 

Seed collection steps:

 

  1. Collect seed heads when they are fully fluffy and dry, but before they blow away.

  2. Clip heads into a paper bag or tray and allow to dry for several days indoors.

  3. Gently rub or shake the seed heads to release seeds.

  4. Separate seeds from fluff using a fine sieve or by gentle winnowing.

 

Germination tip:

 

  • Benefits from cold-moist stratification for 30–60 days but may germinate without it.

    • C(30–60): Stratify in moist medium in the fridge or sow outdoors in fall.

  • Seeds require light to germinate, so surface sow and press gently into soil without covering.
