I'm kind of wondering where y'all got your seeds. Did you buy them online or in a garden center? Just asking b/c maybe the seeds weren't viable to begin with. Could happen.
Many people do grow A. tuberosa from seed. There's actually a thread somewhere here specifically for growing Milkweeds. Also, someone somewhere recommended a website that is all about growing milkweed.
Let me go find the links and will come back and add them.
Ok. You are in the right forum 'Gardening for Butterflies, Birds and Bees'. Within the forum there is a thread called 'Growing Milkweeds'. Bet you could get some good advice there. And that happens to be where I saw the post with the link that I mentioned.
