I bought swamp butterfly weed (Asclepias incarnata) and Asclepias tuberosa; both germinated well; but, as expected in the hot/humid climate in South Texas coast, the swamp milkweed survived propagation from seed very well, but some of my Asclepias tuberosa, are looking puny, since they were in 4" peat pots a little too long. Some were planted a few weeks ago, and are doing well. Others, I've had to discard--looked pale, maybe fungal problems. The incarnatas are doing well (hence the name "swamp milkweed").

I tried to follow your directions about cooling the seeds and then planting However after 3-4 months time the plants are few and only about two or three inches tall. There are no butterflies near the plants.I hope htey make it thru the winter and maybe next year will be better SF
