As luck would have it, I finally found some p. tenuiloba seeds online, so ordered a few. Lots of butterflies host on passion vines but I especially hope to attract things like Mexican Silverspot. Last March a resident of the nearby Terlingua Ranch photographed one at his place.

It would be a lifer for me. Besides, it's fun to grow different things, and I love vines anyway.
