The tag it came with only gave the latin name no cultivar name. It is about 18" tall, but is it short because it is in a small pot? Will it get bigger in a larger pot? It has the shiny dark green leaves like other Peace Lilies but they appear to be narrower than leaves of other Peace Lilies, it produces the white Spathes just like the others. The only thing I know for certain is that it is not the Spathiphyllum 'Domino' (Peace Lily) because the leaves on mine are not variegated. Anyone know how to ID this one?
