Nepenthes macrophylla is truly a stunning Nepenthes. This was another species that I had to have! N. macrophylla has that highly ridged, toothy peristiome and is similar to N. edwardsiana and N. villosa for which it is a sub-species of.  I grow two varieties. One originated from the Nepenthes Nursery in Germany an my other variety was seed grown from Borneo Exotics. Both plants are slow growing highlanders but do grow faster once they get around 8 inches or so. Each successive leaf gets quite a bit larger than the previous at this stage. I've moved some of my plants around from direct sun to under shade cloth. My smaller plants are under shade cloth because the direct sun in summer heats the plants up and I feel they don't like it. Once they get bigger and are in hanging baskets, then they do fine in full sun. Now that Borneo Exotics has this species in tissue culture, the price is coming down but is still an expensive species. Because it is extremely showy and slow growing, the price should remain relatively high for some time. The natural hybrid N. X trusmadiensis (N. lowii x macrophylla) is the only hybrid I've seen in cultivation and that plant is extremely limited. The good news is that Exotica Plants in Australia is making a lot of fantastic hybrids using their N. X trusmadiensis that are phenomenal. I would consider N. macrophylla one of the showiest and a must for the collection if growing highlanders.
