Here is my Sunset. It is actually a shade more chartreuse and the tips are redder than this photo shows.
After doing a lot of looking on the Euro sites, I think it probably is a species but it is not the one pictured from Val Minera by Banker 07 on our page.It is not the one on Sempervivum list which is also different than Banker's photo. It does have red tips but they are not the fire engine red in Bankers pic and they do not extend so far down the leaf. Mine does not change color in winter like the one on the "Liste" Bankers photo also shows a somewhat "flatter" form. My Sunset is almost round like a ball. The base of the leaves in Bankers photo are almost yellow where mine is chartreuse green. I have Royanum which is also a wild collection that somebody decided to name. It is flatter in form, like Banker's photo, it is a paler green color and has very small dark tips. I bet there are many many variants of tectorum in the mountains of Europe. I saw how native species vary from one cove to another in the mountains of North Carolina. I can only imagine what potential there is for variance in the mountains of Europe. I will take some comparison pictures later today which I will send from my phone. I have to go to market now. I think my Sunset came from Squaw Mountain and has not changed at all over many years. Still just producing 3 chicks per year
I need 50 stock plants at the rate that I can sell them.
