I have read through this entire thread. I was going to give Wild Horses a poor review, but after reading that other people in my zone grew it successfully, I might give it another year. I love the pictures of this cultivar and was so looking forward to enjoying its blooms.
I bought four fans of Wild Horses last spring (2020), and it has done essentially nothing in my garden. It isn't thriving, hasn't increased, and hasn't come close to sending up a scape. In fact it looks worse today than when I got it.
I assumed that since Wild Horses is a evergreen that it would grow well for me in zone 8b, but no. In fact it died back over the winter, and I thought I had lost it. It did come back, but it's smaller than it was. I thought maybe it wasn't getting enough sun, so I moved it to a sunnier bed earlier this spring, but it still is just sitting there. Now I wonder if what I received is actually Wild Horses. I may give it another year, but if it doesn't do anything, I'm going to get rid of it.
