Wow, is that yours, Clue? That's gorgeous!
Hey Zu, yeah, it is, although I can't take any credit in the
N. campanulata plants as they're recent acquisitions. Putting the arrangement together was certainly fun, I should have taken some pictures of the process (especially smashing the tufa for the miniature cliff). I fear that as the plants get larger, the aesthetic probably won't be as effective, but that is if I don't kill them first!
@Clue I see burnt earth as media!
Sharp eye, Cindy.

Burnt earth isn't available in the US, but the vendor I bought the BE plant from actually brought back a few bags of burnt earth from Singapore to test on the species (he wasn't having much luck before in sphagnum mixes). Pete: His mix is burnt earth with Orchiata (pine bark infused with dolomite), which I simply transferred into the planter. It's been interesting trying to figure out a watering schedule for this mix.
I've found that it really responds well to limestone chunks in the media. I do think that there must be something in the limestone which promotes growth of this species, as it has certainly responded very well to the limestone.
Do you have other plants of the species in more conventional sphagnum mixes, Natch? I'm not trying to be dismissive of the limestone addition, but I've heard a lot of conflicting reports on what the species actually needs and it could just be that your plant took a while to settle in to the new conditions before taking off. On the other hand, the vendor I received the BE plant from claimed that
N. campanulata would grow well in sphagnum mixes for several months before a slow but inevitable decline and credits the high mineral content (he said water flushed through it was ~200 ppm I think) and looseness of burnt earth for his more recent success. I really have no opinions on the growing medium for
N. campanulata, but I wasn't willing to throw away usable mix (especially when burnt earth isn't something you can get again stateside).
Also Pete, any updates on your plant? I had a few outdoor
Nepenthes plants several years back that were dropping roots because it was too wet and they had similar damage.
