Texas milkweed has an extremely narrow native range. Historically the plant has grown only in Texas. Within Texas it is said to be native to anywhere between thirteen and sixteen counties depending on the source. Texas milkweed is a perennial that local texans say will produce a specific amount of seeds in its lifetime and then die. Your plant may produce all its seeds in three years or it may take fifteen years to produce the seeds. The result is the same. It will fade away having hopefully reseeded itself into the landscape.
Although Asclepias texans has a history of growing in an extremely small geographic region. The plant seems to thrive in the care of a tentative gardener. The first place I ever saw Texas milkweed was in the University of Nevada Cooperative Extension milkweed test garden. You can listen to the podcast to hear more. The garden manager said that Texas milkweed does very well growing in Las Vegas. The plants they have are under the canopy of a large tree and on a drip line.
Not only do I sell Texas milkweed. I also grow them! 2020 Is my first year having seeds for this wonderful milkweed. Most milkweed seeds respond very well to clipping and water germination. Texas milkweed is no exception. From 34 seeds I am now growing 19 plants. As is often the case with milkweed there are inevitably some seeds that don't germinate when expected or that germinate then fade away.
Although Austin TX is in the native range of Texas milkweed. I have not seen it anywhere in the wild yet. Fortunately Texas milkweed can do very well in a container or in the garden. I have been told it doesn't even like growing in it's own native soil. So garden soil it is for the plant!
