- Melissa L.Verified BuyerRated 3 out of 5 stars8/7/26I will endeavor!
I either didn’t do it right or the seeds were too old, because NONE of them sprouted. It happens, so I will try again next spring! I will reorder them next fall and spout them out for planting next spring. I’m sure they’ll grow!

I am so happy that all of my milkweed sprouted! I have never had much luck trying to grow this great little plant, but I did all to the thanks of great seeds from epic gardening. So get over to them and get those seeds heading your way!
