Looks like a rosette to me

Hello RainForestGuy,

Nice plant! I also hope the variagation remains stable as the plant grows. Which one is it, sans. robusta?

Cheers,

Marlon Machado.

This is a robusta, from a leaf. Leaves with a stripe in them unlike the laurentii types usually produce variegates in their offspring.

I had a S. patens (aka Ed Eby) variegated that had a variegated leaf and so I cut it off and rooted it. It made about twenty babies that everyone had variegations on it, some marginal, some pin stripes, some marginals, and some almost solid yellows, very few mostly greens.
The variegations with the non-chlorophyll tissue types usually always produces true variegated offsets from a leaf cutting.
The trif. laurentii with epidermal variegations do not produce true variegated offsets.

My you are so lucky. Congratulations

If you ever get a stripe on any of the cylindrical rounded cross-section leaf, cut it and root and and stand back! Lots of pups and because of the kind of variegation it is, it will proliferate true to it's progeny. Of course you'll get some solid albinos and solid green leaves but you can always weed these out to encourage new shoots in developing evenly distributed variegations.
