Nepenthes platychila was released for purchase maybe back in 2007 or 2006 as a new species from Borneo Exotics. They were very expensive and then once they got into tissue culture the price has dramatically come down. This species produces vastly different upper pitchers from the lower pitchers much like N. eymae does. The lowers are cylindrical but the uppers get a flattened peristome similar to N. jacquelineae does. What I have found is the species seems to grow better slightly on the warmer side than other highlanders. During my winter months, it definitely slows down and doesn't like those nights in the low 40's for lengths of time. It can tolerate the low temperatures if the day time temps get back into the upper 60's at least. Other Nepenthes like N. fusca and N. vogelii grow very similarly to N. platychila for me. My plants are still small and have not gotten into the vining stage and producing uppers yet. They will in time once they settle in and deal with my colder winter temperatures.
