The Dianthus barbatus Green Trick® or “Green Ball Dianthus” was discussed at length on the prototype for the Dianthus Forum at http://davesgarden.com/community/forums/t/1050879/ and I included pictures and language translation for non-English websites. We now have a Dianthus Forum at http://davesgarden.com/community/forums/f/dianthus/all/ which is why I became aware of this thread when it was moved to the new forum. This demonstrates why we needed a Dianthus Forum.

The normal D. barbatus has exactly the same green-ball growth but it is covered with flowers and is not that obvious. I strongly suspect that Green Trick will never set flowers and can only be propagated by vegetative methods. I have attempted to propagate Green Trick almost ten times now using every part of the plant I can think of and nothing works. I can keep cutting of the green-ball alive and growing for as long as two months but the cutting never set roots and eventually die. I have used rooting cocktails which will grow roots and a billiard ball to no avail. All we need to do is get roots on one plant and then layering should work after that. I believe that Green Trick is being propagated via tissue culture.

Note the cuttings in the next picture. Could this be in preparation for cloning?

Has anyone had any success with cloning?
