I've got several of these plants and have found them to be butterly attractors. I've never seen a monarch "cat" on them because I've got several other types of milkweeds including the Mexican milkweed. That one seems to attract the egg layers. However, I did transfer a "cat" to a texana inside a cage and they adapted nicely.

Texas Milkweed is a very rare, but showy milkweed. If it is not flowering it can fool you into believing it is a chile plant or just a plain weed, so if you see something that looks like a wild chile rip a leaf off and if the milky substance oozes out (even just a little) you've found Texas Milkweed! It is native only in Texas in these counties: Bexar, Travis, Williamson, Kerr, Bastrop, Comal, Kendall, Bandera, Gillespie, Llano, Uvalde, Real, Jeff Davis, Brewster, and now Cameron. It is Great for butterflies (especially the monarch) and is well behaved! If you live in Cameron county, you may need to use Cold Moist Stratification on the seeds so they grow.

Added: Texas Milkweed is not native to Cameron County, Texas, but I am growing some here and they are doing great! We hav... read more

Texas Milkweed, sometimes called White Milkweed, is a Texas native endemic plant. I've seen it growing in the Hill Country of Texas, including my own property. It can be beautiful when it's blooming and even the foliage is attractive! It can tolerate the heat and poor soils of this area fairly well, but doesn't form large colonies, just more likely scattered plants or a few here and there. It doesn't produce a lot of seed (just from what I've seen), which limits the number of new plants. If you're lucky enough to have any of these or can acquire any, take good care of them, because not many people have them. It can be grown from seeds and transplanting it is surprisingly easy, considering it's a milkweed.
