SunnyBorders said:I'm a bit confused by "the current batch"; even two (latter, if the second picture shows two babies/spiderettes).
If this is a genetic mutation (a reversion), would all (or even more than one) of the spiderettes likely be reverting at the same time?
Spontaneous mutations are rare events. The form of variegated spider plant shown is the cultivar 'Vittatum' (the variegated form of spider plant which first became popular; no green pigmentation down the centre of the leaf nor in the stems). Classically, mutations are spontaneous changes in genetic material and it then requires selection by breeders over generations to fix them in stable or relatively stable offspring.
If a non-mutational environmental event was involved, the most obvious possibility would be the move to more light (viz. perhaps less demand for photosynthesizing tissue). Of course, the situation could conversely be a change to too much (direct) light for a spider plant.
I'm taking it that an apparently sudden change does suggest a mutational event.
SunnyBorders said:In a garden situation, such phenotypic changes usually seem to be quite rare.

Relevant here: we're not talking about years and years of artificial selection by thousands and thousands of plant breeders.
TheWitchBoy said:Hey, I just wanted to pipe up (since no one seems to have, yet) that some variegations of spiderplant actually start variegated and revert to an unvariegated format. For example, the Hawaiian spiderplant is a green spiderplant that gives of variegated pups, which then grow up and lose their variegation (and proceed to shoot of variegated pups, ad infintum).
So! It miiiight be possible that you have a Hawaiian spiderplant (though I note that you said the first -few?- pups from your plant weren't variegated).
Whatever the case, best of luck with your spidey!
