Interfertile means when any two nepenthes really love each other, one being male the other female, they decide to have nepenthes love. Nepenthes don't care about their differences, when it comes love. Because in the end, they're just desperate for anything! Soon after that special moment, the male grows tired of the female and starts looking for other things to do, such as bother his grower by producing smaller leaves for no reason at all. Meanwhile, the female nepenthes produces tons of seeds! Which soon after, are quickly wisked away by the ebay stork and sold to people all over the world!
