Milkweeds can certainly be hard to grow. Some require a certain kind of habitat. I have trouble with Swamp Milkweed Beetles and larva eating my milkweed during some years. And A. texana doesn't easily produce seeds. There has to be enough other A. texana plants around that bloom at the same time...then some may have to be cross-pollinated by hand if there aren't any insects around that can do that. I have other species of milkweed vine (besides F. cynanchoides) around , but have never seen the Monarchs or Queens lay any eggs on them. The Queens have chosen to lay eggs on F. cynanchoides vines in the past.
