Fred's Redhead update (2 pics)

I've ignored my plants during the last months so I've been making some changes, sorting out, transplanting. Today it was the turn of these lesliei. I've separated the bigger and stronger seedlings from the weaker ones (it was getting too cozy in the pot). 
It's curious how only the parts exposed to light get the dark color (I guess, much like optica v. rubra) while the rest stays green. The one pale seedling to the right probably resembles the "regular" ancestors of the cultivar.

PS: I've read that valerian flower extract is very good for cacti and other succulents. Anyone tried it? I've ordered it and will report on the possible changes. :)
Thanks for your comment
