Downy Wood Mint (Blephilia ciliata)

Difficulty: ⭐⭐⭐☆☆  

Seed Collection Time:


Mid to late summer — typically July through August, after flowering ends.

 

Signs seeds are ready:

 

  • After blooming, the plant forms rounded, tiered flower heads that dry and turn brown or tan.

  • Seeds (technically nutlets) are tiny, hard, dark brown, and located at the base of each dried floret.

  • When mature, seeds fall out easily when heads are gently shaken or tapped.

 

Seed collection steps:

 

  1. Clip dried flower heads when they are fully brown and crisp.

  2. Place in a paper bag or tray to air dry for several days if not already dry.

  3. Shake, tap, or rub the heads over a container to release seeds.

  4. Clean seeds using a sieve or by winnowing to separate from chaff.

 

Germination tip:

 

  • Benefits from cold-moist stratification for 30–60 days, though some fresh seeds may germinate without it.

 

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

 

  • Seeds are tiny and require light — surface sow and press gently into the soil.
