I should think that after being in water for several weeks, if the
leaf isn't starting to rot by now, then it's probably a viable leaf.
I've never started African violets by putting the leaves in water,
although I have started plants by planting the leaves directly into
potting soil. I'm not an African violet expert by any means, but I do
keep a few plants. They were my mother's favorite plant — mostly
because it was the one thing she couldn't kill. You can read a story
about my mother and her African violets he

Good luck with your African violets!
