I got one like that from a seller; he included it in a shipment as a bonus.

I put it in water prior to planting, and it wilted almost immediately, then rotted.

Some kind of environmental damage - did you water it with cold water?

Leon - the one you got - probably got damaged in shipping - exposed to cold or heat.. Some plants are more sensitive...

I started it from a leaf, and I have another one like it, in the same location in my house. I have four others in a different part of my house, with my older violets, and they are fine. I think I'll just toss them to be sure and sterilize the area. I have plenty more. But just was wondering if anyone else had this problem.

No, I use room temperature water.

Did the damage appeared literally overnight? More chances that it is some kind of damage - mechanical or from cold. Did you do the cleaning and sprayed something near this place with 409 or Windex?

It does'nt look like a disease - but if you have spares without damage - chuck it for the sake of peace of mind.

Found an explanation on Russian site.To prevent spotting the AVs should be kept evenly moist. If you dry them to dust and then try to water again - you need to rehydrate them gradually, otherwise the fast absorption of water bursts the cells and damages the "skin" - cuticle, the damage heals with the cork type tissue - yellow spots. Even if you didn't dry them - but abundantly watered in the evening - the leaves start "sweathing" excessive water out - this process is called guttation. With the cooler temperature in the night time - these wet areas get chilled. Similar situation - if you water - and then open the windows - if the air is chilly -even it is above freezing - the wet areas get damaged.

So = wick is better than bottom watering because there is no drought to drown changes in a soil. If you water from the bottom - do it in the morning - and do it sparingly. Even moisture is good. Too dry - too wet - jumps are bad for many reasons Dry plant is more resistant to the drafts from the open window than a well watered one.

No, I really pay attention to my violets, and water them before they get bone dry, and never let them sit in the water. I don't get water on the leaves, and use room temperature water. It's just this one group that I started from several leaves that has this problem. I'm thinking it came with the leaves that someone gave to me. I have thrown two of them out, and have just now removed a few leaves from the four others that look suspicious. I looked the disease up on a website, and it is a disease. I'm on the verge of throwing the rest of them out. They are isolated from my other violets, and I don't want it to spread. I'm going to look up the name of it again, and post it here. Don't recall it offhand. Stay tuned!

OK.....I looked it up on optimara.com, under diseases of the leaf. It looks like leaf nematodes.

What kind of disease you think it is?

When these new starters bloom - do they bloom nicely - or you see mottled distorted flowers? If it is the case - chuck them and soak pots in clorox.

I.

The blossoms are beautiful and not spotted. I have an even temperature/AC throughout my home. No chilly nights. Water is room temperature. I didn't throw them out, I'm watching them. There are quite a few bad spots on/in the leaves. But not all the leaves.

If the new leaves come without spots - there was something in culture - season related - your collection is healthy. Cold nights are not contagious...

Good Job!
