A few days ago, I planted the one packet of Asclepias tuberosa (butterfly weed) I was able to find. I have never grown it from seed. Today I spoke to 3 different friends about this species. They all told me they had tried to grow it for years with poor to no results. Two said they think it needs cold stratification although their experiments yeilded few plants. One is going to try winter sowing later this year.
So...has anyone had good luck growing Asclepias tuberosa from seed? Any tips? I found another 3 packs of seed and want to hedge my bet.
