A few months ago, I propagated new African violet plants from leaves of a single specimen. All the leaves grew successfully into new plants and they live in a corner of the kitchen under the south-facing window, with another plant many years old. The leaves are a beautiful medium green and are particularly large. Recently I noticed that the leaves had suddenly faded to the palest green with a dark edge, and where a leaf overlapped another, the darker green colour had remained. I observed this at different times of day and night and have come to the conclusion that as soon as natural light goes at sunset, the leaves respond to the artificial fluorescent light in the kitchen by going pale. This in itself is fascinating, but even more so is that none of the other plants do it, even those propagated at the same time. I would love to hear from an expert what their opinion is on this phenomenon.
