Nepenthes X edinensis is a hybrid between N. rafflesiana and N. X chelsonii. N X chelsonii is a hybrid between N. dominii X N. hookeriana. N. dominii is hybrid between N. rafflesiana and N. gracilis. N X hookeriana is a naturally occurring hybrid between N. rafflesiana and N. ampullaria. Phew! I didn't know all of this. I got this information from Gordon Cheers' book A Guide to Carnivorous Plants of the World. He has a nice section in the back with all kinds of parentage of hybrids and species. I received this plant in trade from the Frederik Meijer Gardens in Michigan. They were referring to it as N. X edinensis so for a long time that's what I was calling it until I saw Sunbelle Exotics N. X edinensis. It looks nothing like the plant I have as compared to the original Victorian hybrid. I agree with Trent (Sunbelle Exotics) that whatever this plant is, it isn't N. X edinensis. You can see their plant in their gallery section of Nepenthes at their website. Whatever this hybrid is, it has had no trouble adapting to outdoor conditions. It appears to be a moderate to quick grower outdoors and definitely likes to climb by wrapping its tendrils around anything. The newest photo shows some striping in the peristome for the first time. The peristome is also flat in relation to the pitcher that I think is kind of cool and different.
lowlander / intermediate / highlander?
Cultivation: easy; moderate to quick grower outdoors,
probably fast grower in typical lowland conditions
Market availability: no clue. complex hybrid that would be difficult to duplicate, available from cuttings is my guess
Species variation: none that I know of
$ / size: traded out for this plant. I don't believe it's something extremely rare and is purported to be a rapid grower which would increase cutting availability
Cuttings: none available for trade
