Several months ago I was going to post this as the ugliest chimera African violet bloom I ever grew or for that matter saw. This was a sport of Yukako. I normally would discard the plant but was fascinated by the foliage which also appeared to exhibit a chimera pattern. Long story short the plant bloomed again and this time produce much larger blooms (below).
As is evident in this bloom it appears the border of the bloom is black. A closer view of the bloom below shows this more clearly, note the flower edges under letters “A” and “B”. Its black is most pronounced.
Based on my own conjecture as this is a sport of Yukako produced by stem culture and because there are multiple colors involved in the bloom, I believe this is a chimera African violet hence the black edges cannot be breed into another plant. Now all this said at the writing of the above 2 weeks prior to this observation (below) I saw two bloom stalks popping up. I figured I will let it bloom prior to pitching the plant. Of course the color was not any different but the number of petals expressed on the first bloom of each stalk has seven! The rest of the blooms had the standard five. See the image below.
So now what? Do I discard the plant or try propagating the bloom stalks with the first bloom of seven to see if this can be reproduced or this was just a fluke? Of course! Lets propagate the bloom stalks to see if the seven petal bloom is real (genetically driven) or not. As a footnote the black as seen under a little different lighting has stronger green coloration in the above image.
