N. bongso lower pitcher
This species is quite beautiful.  Its leaves are thick and rubbery, and pitchers are rather stout.  In bright light, the pitcher peristome darkens considerably over a period of about two weeks, until it is nearly black.  Its rate of growth is steady; we have grown this plant from 4 cm diameter to full size in approximately two years.
