I have Phlox Pilosa "Slim Jim" in full blazing sun and it does great, but it only blooms for a while. If you want something that blooms ALL season long, try perennial moss verbena.

I don't think it will be as hardy as the Datura. Datura can grow anywhere. If it doesn't work out you can always but the datura back.

Cynthia - I don't have those varieties of euphorbia, but I do grow a couple of other varieties and they do great here. I bet you will have good success with your euphorbias. They are a nice unusual accent plant.

Many Euphorbias can not take the heat and sun of Texas. E, rigida and E, myrosintes can but I don't know about these others. Good luck. I have killed a few of the other types but not those listed. I am pretty sure the polycroma will not take the heat. I can't remember where I heard that

I also Have grown Phlox pilosa in the sun and the shade without any extra water.. They are getting ready to bloom as I type. It is a spreader.

Bluestone Perennial is from Ohio. Their concept of hot and dry is different from a Texan's idea of hot and dry. So be careful.

thank you
My order didn't go through, so I will try something else. I looked up the phlox pilosa and that doesn't look like the one I have. My leaves are smooth. I'll try a few babies. Going to plant some verbena on the strip too and other hardy pers.

Y'all are a wealth of knowledge and experience.
