It sure is a cool Aeonium Andy. Fun to see how it color changes depending on the season:
Have repotted it and took some cuttings as well in late Fall last year, and planted it with Aeonium hierrense.
This is how it looked like in Jan 2015:
Feb 13, 2015
June 3, 2015 - really very dark and almost black, but actually it is more like deep, deep burgundy color
I plan to move Aeonium hierrense in a different container this Fall and consolidate all the A. arboreum 'Zwartkop'
