Unstable variegated Tonina fluvatilis, my failed attempt at making a new cultivar.
So this plant here is a marbled/non-patterned sectorial chimera of a white mutation and normal Tonina fluviatilis that is not stable.
A chimera is any organism that has two or more sets of genomes in it. In this case, normal green Tonina fluvuatilis as one and a white mutation as the other. Marbled/Non-patterned-sectorial is a word to describe how each of the genomes are spread with in the shoot tip (Shoot Apical Meristem) which makes the whole plant, it means you have a random mix of each. Not stable here means that eventually the green tissue divides faster than the white so the ratio of green to white goes towards green as the plant grows, eventually being all green and of course never reverting back.
No matter how many sideshoots I tried or in what conditions I grew it, I could not get it to show a stable pattern. So it’s a plant that wasn’t meant to be.
A word on the how-to: By sheer luck I found a streak of lighter colored tissue in a stem of Tonina.
I recognized that streak as a chlorophyll mutation and in an effort to get a sideshoot with more of that mutation I forced that stem to sprout from a node where the lateral bud intersects with the white streak. Eventually, the shoot above emerged as a sideshoot of a sideshoot.
While that it is of course sad it failed, I did gain a nugget of knowledge: The marbled cultivar “Tonina fluviatilis ‘Marble Queen’” is most likely not a chimera, because it is stable, unlike my chimera here.
