This plant prefers intermediate/lowland conditions. It should be kept between 80-84F in the day and doesn't require nocturnal cooling. Nepenthes can acclimate to lower humidity levels, although the best results will be seen with a relative humidity range between 75-80%. Bright, indirect light, and pure water.
We only got these in on our spring import and they show a wide range of features. The merrilliana is buried in there, but these still have the potential for very large pitchers!
Exact plant as seen in the images. 6+ inches in diameter. Shipped with roots wrapped in sphagnum.
