I have grown it on a caliche limestone out cropping. I likes a slanted outcropping that has moisture moving across it. It took more than a year for it to germinate. I forgot about it. It is dependant on a warm rain for it to germinate. It was a beautiful surprise. Not to be depended on. A very special plant.

This plant is also know by the name "Catchfly". The stem exudes a sticky sap that captures small insects that try to steal nectar without pollinating the flowers. Hence, the common name Catchfly. I found the seed at http://shop.Wildseedfarms.com. Haven't received it yet but will let you know how it turns out!!

I've never grown these, but they are native to my area in Texas. They are commonly seen blooming on the sides of the road in fall, most of them making the cutest little vase-shaped plants, just like natural bouquets. They seem to take drought fairly well.
