Golden Sedge (Carex aurea)

 

Seed Collection Time:


Mid to late summer — typically July through early September depending on location.

 

Signs seeds are ready:

 

  • Seed spikes turn from green to straw-colored or golden brown as they mature.

  • The perigynia (seed sacs) become dry and papery.

  • Mature perigynia detach easily with gentle rubbing, and the seeds inside are firm and dark brown.

 

Seed collection steps:

 

  1. Snip mature seed spikes with scissors when they begin to dry and change color.

  2. Place heads in a paper bag or mesh container to air dry for 1–2 weeks.

  3. Rub or gently crush seed heads to release perigynia.

  4. Use a fine screen or winnow to separate seeds from debris.

 

Germination tip:

 

  • Requires cold-moist stratification for 60–90 days.

 

    • C(60–90): Store in moist medium in the refrigerator or sow outdoors in fall for natural overwintering.
