Hi George,
sorry for answering your  e-mail so late. I had not read it until now. I
still have many of Cactus_etc that I have not opened.
Anyway, Sansevieria trifasciata 'Laurentii' will definitely not produce any
variegated plant since the variegation in on the first (outermost) layer LI
(ell one) that forms the epidermis of the plant. The genetic tissue, which
forms the flowers and seeds, is usually on LII (ell two) and therefore a
seed will only be green. S.t. 'Bantel's Sensation' second layer is white,
but in my experience, inflorescences grown off this plant are always green.
Because of the unruly growth of the layers of this  very particular plant,
I think that an inflorescence usually grows off a green area, where there
could have been an encroachment of cells of the other layers. If you do not
believe this just cut a section of a leaf and see that the layers are not
neatly arranged as they are in all other periclinal chimeras, of which
'Bantel's Sensation' is one. If this is confusing, let's say that the
layers are not as neatly arranged as say, S.t. 'Golden Hahnii' which will
produce a yellow inflorecence because LII is yellow.
Therefore, the inflorescence of S.t.'Bantel's Sensation' is usually green
and to my understanding will only produce green offsprings unless, you see
that the inflorescence is variegated. One has a much better chance with
mericlinal chimeras, that is those that have random stripes of variegation,
as S. t. 'Wagner's Gold', etc.
Take a look at the inflorescence, after all I said, the flowers stalk may
still be variegated, in which case is would be worth to self- or
cross-pollinate it.
Regards,
Juan
