Nepenthes deaniana is a lowland species that I have had nothing but troubles with! I started out with my first one about two years ago. It was shipped bare-root and upon arrival I potted it up. Within 1 day it wilted and went into severe shock. That plant died about three days later. I've never had a Nepenthes disintegrate into death that quickly. So, of course, I tried another one. The same thing happened! I can't remember if my vendor gave me another one for free to try again. If he did, that one kicked too. So I gave up on N. deaniana. Now two years later I figured I'd try again. The plant I received arrived healthy and potted up fine. There was a miniscule amount of leaf wilt, but nothing major. It adjusted to windowsill conditions and pitchered up for me. It began to outgrow the windowsill so I moved it outdoors. One of my vendors said that his plants could take lower temperatures. It has adjusted to outdoor conditions and is doing fine. When winter comes, it stresses and should be moved indoors due to the lower temperatures. While it did stress in my highland conditions it has done well when spring temperatures returned. For best results, this plant should be grown as a lowlander and possible intermediate only because my plant has withstood some wintertime low temperatures. I was also told that N. deaniana is in some state of flux as to species status. I'm not sure if my vendor was referring to the species as a whole, or to the plants he received from Borneo Exotics. My suspicion is that it is the whole species. Whatever the case, this plant I have was sold to me as N. deaniana. Another interesting twist was the fact that I saw a website that had N. deaniana growing between 1300 - 1500m in its native habitat. That would make it an intermediate to possible highlander. But I've always seen N. deaniana listed as a lowlander. For some reason there is a lack of literature about this species. I would consider this species susceptible to transplant shock fairly easily. It doesn't like its roots disturbed at all. Once acclimated, it shouldn't be too difficult to maintain from most of the feedback I've heard.
lowlander / intermediate? 1300-1500m
Cultivation: easy to moderate indoors; moderate
outdoors at first; once established grows fairly quickly; move indoors during cold months.
Market availability: size 3 to larger plants; fairly common
Species variability: none that I'm aware of
$ /size: moderate $25.00 and up for larger specimens
Cuttings: none available for trade
Notes: seems to be prone to transplant shock; disturb the roots as little as possible
