I've seen rot, bleaching, and just age creep up on leaves. As lucky said, it can be different from leaf to leaf.

Check if they're still crisp, look if there are any roots visible (clear pots can be so helpful ;-). ) you can tug on them to see if they are rooted, but that may damage very fine roots....

Decide if your leaves may be getting too much or too little light. (Are only the lighter coloured ones affected?)

If the issue isn't any of the above, and you're using a soil mix you know (as in, you're pretty sure it isn't a PH issue) consider adding a little bit of fertilizer or Epsom salts next time you water. This will only work if the leaves have roots though (and if the cause was nutrient imbalance).

Other than that, patience is key.

Good luck,

And its entirely possible the leaves were 'old' to begin with - taken from the outside row on a plant - and the yellowing has nothing at all to do with your care. Still, I've had leaves that looked like that send up a baby or two. As long as they're not mush, there's hope.

thanks all! they are very crisp still and i think all of them have rooted although they took longer than usual to do so. andyes... they were all BIG leaves so its possible that they were old!

Just my opinion, but just as some violets like being near a window and grow wonderfully, sometimes you get that violet that doesn't want quite so much light. And you have to move it back some. That is what it looks like to me. A little too much light.

Only reason that hits home with me is I have a violet that behaves like that. I haven't tried to start one of her leaves so I don't know how it would behave,but it could be reasonable to assume that a leave could be like that also. As everyone else said,,,,,if the leaves are still good, not mushy and overall fine I would wait to see what happens! Rosie

PS. WOW wouldn't it be neat if those leaves produced something entirely different than what your original plant was? I mean something so different it would not be a sport,,,,,it would be a mutant!!!!!! Something no one has ever seen before!!!!! lol

Ok, I have an update on a violet getting too much light. I just had a violet bloom (a beautiful red---bought her at a groc. store, hmmmm tag said from Canada. Harsters???) but her leaves are toward the yellow side. Not the nice green we all strive for.

I moved her from the windowsill (unobstructed east window) back about 3 feet to a table. Her stems and leaves are very "stiff" (turgid?). Not unhealthy in a going to die sense,,,,,,,just is getting, in my opinion, far too much light. It has happened before to a couple other violets and moving them out of direct light has fixed it.

Also I may need to feed a little. I don't feed during the winter months so I am just getting them back on summer growing. Anyway, she is really pretty!!!!! Rosie
