Red Hot Pokers

I have some Red Hot Pokers in my garden, otherwise known as Torch Lily or Kniphofia uvaria.

They have seeds on their stems and want to try and grow more plants....

Seeds may be sown at any time. The seeds need 6 weeks of moist chilling in
the refrigerator, prior to planting. After sowing, keep them at 70-75 degrees F.
Germination normally occurs in about 20 days, but may take up to 3 months for
certain cultivars.


I wonder if I have to wait if they have dried first?
