Most of all the "gaga" over N. rajah is just that. Although at one time, it was thought to have the largest pitchers in the genus, there are others that rival N. rajah in size. Large pitchers have been found on N. merrilliana, N. rafflesiana giant forms, and N. truncata can certainly look spectacular as an adult plant with adult pitchers. Nevertheless, for those desiring a slow growing highland nepenthes with a long long waiting period for it to mature, N. rajah can be rewarding. Personally, I think pitchers of N. trancata, and N. veitchii are both nicer looking pitchers. Remember....."Beauty is in the eyes of the beholder."
