From an email back when I tried groiwn pervillei. (I lost mine when I went out of town and it froze when the heater went out.)
>indeed I have N. pervillei in my collection since 1990, when a tiny
>seedling
>(4 cm diameter) from the Botanical Garden Essen (Germany) arrived. 1992 we
>took a trip to the Seychelles to produce a video on the pitcher plants.
>From
>our Mountain guide we received some seeds from the Morne Seychelloise (on
>Mahé), which germinated very good, and now - 10 years after germination -
>the plants start to produce the many meters long vines from a basal
>rosette.
>Every 30 to 60 centimeter new rosettes (25-35 cm diameter) appear, carrying
>now the typical amphora-shaped pitchers, hold upright by a small tendrill
>near the end of the leave. The clones from top of Morne Seychelloise (>
>1000
>m, Neps from ca. 500 m) are more robust and produce bigger pitchers, than
>those of the other growing site on Mahé Mount Copolla (approx 800 m, Neps
>from ca. 350 m). However, the last site is much easier to reach. For the
>higher Morne Seychelloise a guide is recommended, as the way can be
>slippery
>and dangerous.
>
>The Seychelles are placed just a little beside the equator and temperatures
>are nearly stable around the year (28 - 32 centigrade at the coast). The
>mountains are frequently clowdy or misty, but when the sun comes through,
>also in >600 m its getting hot. On our visit, clouds and heavy rain for
>minutes changed all half an hour into blue sky with burning sun and
>reverse.
>With clouds the temperature lay around 22-24 at the site, during misty
>nights, also 12 degrees are possible.
>
>My plants grow together with lowland species in a greenhouse. During summer
>the dayly temp. in centigrade is between 25 and 37-40 during the day, can
>be
>15 during the night. In winter its around 12 low and 18-28 during the day.
>A
>sprinkler (using deionized water) is installed (and heating in winter) and
>to avoid mould a strong fan is running at daytime. The plants love direct
>sun, however, the basal rosettes frequently place their lower pitchers on
>long tendrills into Sphagnum (or withering leaves), where they grow totally
>submerged, getting dark red to violett in color.
>
>In my opinion N. pervillei is easy to grow if you have the base knowledge
>wich is necessary to grow pitcherplants. I like this unique western
>species
>very much and hope I could help you to keep yours alive.

>The plant reacts positive on Orchid fertilizer (quater-half concentration
>as
>mentioned), from March to April all 2-3 weeks. More can be dangerous, but
>its recommended to feed the pitchers with insects (or dried bloodworms). In
>nature, many birds at the habitat do their duty to fertilize
