How to stratify seeds

Congratulations on your new native plant seeds! 
Some native plants require a month or two of stratification in cold, moist conditions to simulate spending winter outside in nature.

There are 2 main ways we recommend stratifying your seeds (Don't worry, it's easy!)

•  Plant your seeds outside late in the fall (October or November). They will sprout naturally next year!
  
  
•  If you're in a hurry, follow the steps below:

1. Take a cup or two of fine sand and get it nice and moist, not dripping wet, but damp to the touch.
2. Place your moist sand in a plastic bag and mix in as many seeds as you would like to plant in a certain area. 
3. Place the bag in your refrigerator for the number of days your species needs to be cold and damp

             Gray-headed Coneflower- 30 Days
             Common Milkweed- 30 Days
             Wild Columbine- 60 Days 
             New England Aster- 60 Days

         4. Remove the seed/sand mix from the fridge and plant ~1" into the soil. That's it!
