two different clones 

Nepenthes ventricosa X Mixta is a cross between a highlander and a lowlander. Nepenthes X Mixta is an old Victorian hybrid between N. maxima and N. northiana. When I got this hybrid, there were two plants growing. One of the plants had the maroon pitchers and the other plant had the striped pitchers. The person I bought it from said the pitchers start out maroon and grow out to the other form. I think when the plant was purchased from Exotica, there were two plants close together. Many times Exotica will ship you seed grown plants that are close together rather than separate the two. These are "bonus" plants that Exotica is famous for sending. The larger vine is producing pitchers that have a peristome similar to N. northiana while the other vine isn't that exciting. So maybe this hybrid has a lot of variation between the seed grown plants. At first I wasn't that interested in this hybrid, but since it has produced more N. northiana like pitchers, it's becoming one of my favorites. I'm growing this plant outdoors as a highlander year around without much difficulty. Like any intermediates, temperatures into the low 40's are tolerated but growth pretty much stops. 

Cultivation: an easy grower outdoors in typical intermediate temperatures, tolerates lows into the 40's during my winters
Market availability: size 3 to possible rooted cuttings in the future; somewhat available at times
Species variability: maybe some among the different seed grown plants
$ / size: moderate $25.00 and up
Cuttings: none available for trade
Sex: unknown
