@Dogpack. I expected JB to reply, so didn't reply to you...variegation can be caused by several different things, and therefor has a different look. I would say that on the AVs that have a lighter border that could be variegation, but a more classic example is where there are lighter green, white or yellow colors blended in on each leaf.
Julianna and Dogpack, I'd love to see photos of your plants!
Cheers!
