In my travels last night I found this one growing in someone's yard. The owner was not able to tell me where it came from or how old it is.
I am resisting the temptation to call this a new A.Nubile hybrid.
It was growing in his yard right next to an actual A.Nubile specimen. As far as I can tell this only differs from A.Nubile in that the leaves are a slight bit thinner, the rosette centers tightly pucker like a Greenovia, as you can see, and the edges of each leave have the purple coloration, also as you can see.
Your thoughts are appreciated...
