Thanks and the Devil Claws I planted down at my sister's house had the purple undersides. Just a update.
They came from Arizona in a Devil Claws seedpod. Should I put up a picture of the seed pod they came out of?
I haverested the seeds from the Devil Claws seedpods and planted them. i made sure there was nothing there after I cleared out a spot for them. I planted them directly into the ground and I gave my sister some of the Devil Claws seeds also. Could this be a new kind of Devil Claws that is a Hybird? That could be a possibility.
Not that I can see today. When are they supposed to get sticky and Dew Tipped Hairs on them? I will check when I go back down there.
