Highland or lowland?

I would personally classify both lowii and jamban as highlanders. Although, lowii has been found at 3200m asl IIRC. But it isn't a strictly UHL plant per se. That seems to be the farthest end of its range.

Here is my opinion, do note that my area is ultra lowland(the hotter end of the lowland range), if there is such a thing.

N. sibuyanensis --> Will grow lowland, but is more intermediate. Doesn't do well when things get too hot.

N. ventricosa --> Will grow lowland, but is more intermediate. Does better than sibuyanensis in hot weather, but not by much.

N. lowii --> Highland to ultra highland. Will be quite happy with standard highland conditions. Requires a night temperature drop of some sort and days can't be too hot(unless humidity is very high).

N. jamban ---> Will grow as an intermediate, but is more highland. Isn't as cranky about warmer temps as lowii, but prefers standard highland conditions.

Thank you so much for your responses, I think I will grow N. sibuyanensis and N. ventricosa in my lowland terrarium and N lowii and N. jamban in the highland one with a Heliamphora. I hadn't heard about intermediate plants, but I think I will have to construct a new intermediate terrarium, can you tell me the conditions (temperature, humidity, light, etc..) of intermediate plants? and do you think N. jamban and N. lowii will grow well on Heliamphora terrarium?

Outside in San Diego, I've noticed that lowii hybrids (as I don't have the pure species) like it on the colder end of highland, while jamban likes warmer highland (intermediate I'd say). Sibuyanensis likes it warmer rather than colder, and in my experience, ventricosa is happy in intermediate to highland conditions with no difference between the two.

My N. jamban must be the only cranky/picky plant on earth! While it grows like a weed all winter, when the slightly warmer summer temps hit my basement, the N. jamban goes into pout mode. It hates the warmer temps as much or more than N. aristolochioides. The other neps, like N. lowii, N. hamata & N. tenuis are unfazed by the slightly warmer temps ...

Ahh, you are confusing me :smile:

So, is N. jamban a Ultra Highland or an intermediate that prefers warm? I never thought that species would be so picky :turned:

RL7836, what is the highest temperature your Nepenthes jamban stands without dacaying?

I think I will put my lowii and jamban in highland or ultra highland conditions, ventricosa in intermediate and sibuyanensis in lowland.

Wow...over here the day temp can reach 35C and jamban doesn't flinch unless its thrown out under direct sunlight. Perhaps the issue is one of temperature drop instead of just temperature. Here in tropical Singapore, jamban WILL die unless it gets cooling at night but can withstand the day heat if it does.

aristo is another story for me, it just dies when the temp goes up. The only way I've had it survive so far is to shade it during the day and even that doesn't produce decent results.

lowii also won't take high temps for me and neither will tenuis, although hamata is quite happy growing lowland(so far) if the humidity is kept very high.

I suspect that lowii hybrids tend to take on the requirements of the other parent. My lowii x campanulata takes ultra lowland conditions(35C days, 30-27C nights), takes almost direct afternoon sun and is extremely happy with it. I wonder if there are any other lowii hybrids with a lowland parent(lowland, not intermediate) to support this theory.

Interesting- might explain why my lowii x campanulata looks very unhappy in our English endless winter!

By the way, I've got a N. sanguinea growing at 20°C~25°C at day and 9°C~10°C at night and it looks better than any other of my Nepenthes, can I grow my new plants on these contidions?

My bet is that you can. Only sibuyanensis may get cranky with it being too cold(I think it won't but I've not grown it that cool before), but I'm relatively sure the other 3 will be just fine.
