Here is a photo of a root-forming callus (as opposed to those producing shoots or leaves) of the "selfed" seed mentioned earlier. Root formation is often the weakest link in terms of tissue cultured plants; and commercial growers -- to cut costs -- often transfer "plantlets" of many species to compost to root ex vitro. I have found that Cephalotus, in particular, is far more successful and vigorous if there is something more substantial below the soil . . . Cephalotus follicularis "Eden Black x Self" 25 August I was also very encouraged by the bright red coloration of the earliest "vegetative" leaves on another callus, even under the moderate lighting conditions of a growing room:  Here are a couple of other shots of root-producing calli in Muroshige-Skoog-based multiplication media -- both of which currently look like something out of an HP Lovecraft story: 28 August

No, they're in an agar solution, it's like a harder nutrient-filled jelly for plants. It provides a sterile growing medium so plants can stay unaffected by parasites.
