Worthy mutant?

Try looking directly down on it from above and see if new leaves seem to be sprouting/emerging out of the exact centre of the plant, or if you like scientific terms, the meristem/apical tip. Keep a watch there for any new growth. If you can't see anything, then yes, this plant is a "dud", but I would give it another day or two to see if anything emerges, however, seeing as how it has been 3 days already and from past experience with this exact thing, I personally would be considering giving up on it. Sometimes these things occur, just to remind us that nature isn't perfect and to expect some hiccups occasionally. Hope this helps.... Organoman.
