Nepenthes mindanoensis is a plant from the Philippines that really is a lowlander / intermediate. I've experimented with lowlanders outdoors and found Nepenthes from the Philippines seem to adjust to my conditions for crossing over to highlanders the best. This is one of those plants. My smaller plant pictured above is kind of plain and hasn't exhibited the striated coloration of my larger plant yet. To me, this species looks very similar to N. philippinensis and even N. alata "red striped" that I've seen around. I also grow N. philippinensis "old clone" I got from another grower that greatly resembles my larger N. mindanoensis. So they must be closely related. I grow both plants outdoors yearround. I've had no problems with it outdoors during the spring and summer months, but in winter it does stress, growth slows, and there is some leaf damage due to lower night time temperatures. When the warmer months return, so does the growth and the plant is happy again. So this is another candidate that would benefit from being moved indoors during the colder months to avoid damage similar to N. albomarginata and N. longifolia to name a few. If grown in normal household or terrarium environments, I expect this plant to give you no troubles similar to N. alata.
