Hi! Did your S. leucophylla come with the tag 'Tarnok'? I am most certain it is S. leucophylla 'Tarnok'!
Sarracenia leucophylla 'Tarnok''s growth is like any other leuco, pitcher color, size and shape are typical for the species. However, it's flowers are unusual; they're mutated, lacking all petals, anthers, and styles, instead having lots of mutated sepals in their place!! In this case, pollinating these flowers is impossible because they don't have any of the sex organs needed for pollination or fruit making!! The only means of reproduction are vegetative, by splitting the rhizome. : )
