Hello Plantmover, thank you for your comment, I just found your post. I hope you will try it and will have good results, we love our native plants and it is a lot of fun watching the butterflies.
I am fortunate to be in N Central Tx and visited Josephines slope several times. Each time it has something new to offer, and the butterflies love it. Took a picture I took of a Dogface Butterfly on my first visit in 2007.
