Nepenthes lowii x ephippiata is a cross between 2 of the most iconic Bornean endemics. Originally the horticultural cross was done in Europe and then redone in Japan. All the offspring I have seen so far have been intermediate between the 2 parent species. My experience growing the plants to near maturity has been that they are exceptionally vigorous compared to the parent species.
Plants for sale are a random selection of clones from tissue culture.
