My boss won't give away the secret to me for this one, it is supposed to be difficult to germinate. Lemme check with a few other people and see if I can get the trick.
Ok, here is what I got: (Your going to want to get more then a few, even with stratification, as I understand 40% germ rates are still high, 20-30% are more common)
For Common milkweed Asclepias syriaca.
3 part stratification: (some people said no strat is needed, but germ rates are real low, under 5%)
Step 1: Coldmoist for 3-6 weeks - wrap them in paper towel throw them in a bag and put 'em in the fridge.
Step 2: Let them dry up for a day or 2, then scarify, best method I have heard is to put them in a bag with sand, and shake it around for a couple minutes.
Step 3: Soak them in warm water for 24 hours. I would start with something not to hot to put your hand in, and then let it settle to room temp for the rest of the time.
Then after the 24 hours are up.
Sowing: Sow them indoors cover with no more then 1/4" of dirt. You need to keep the soil temp above 75F, and they should germinate within 2 weeks
