Found this interesting branch the other day, it is a top branch where 2 oposite buds have sprouted with variegation, both the leaves and the stem have the variegation. It is only on this one branch, none of this on the rest of the plant.
There is a flower bud which also seems to be white.
I will monitor the new growth of this branch and if it keeps the variegation will try to air layer it.
Just noticed on the pic that the underside of the leaves are also white, compared to the regular one in the photos.
