Pitcher Longevity

[kltower]

I live in Kuala Lumpur. So my lowlanders are of course grown in normal tropical conditions, some fully sunned and some shaded. The highlanders are grown in high-cond room with ultrasonic humidifier to provide humidity of 70% and above. Being in air cond room, the highlanders do not catch as many bugs as the lowlanders where food are aplenty.

Generally, the pitchers of highlanders last much much longer than the lowlanders. Of course, it does not help the longevity of lowland pitchers when squirrels/tree shrews come and chew them up.

The longest life span observed was a ramispina which pitcher in February and only dried-up last Christmas.

These the observed life span of medium-large plants (pitcher size in parenthesis).

Lowlanders
rafflesiana 1 month (15 cm)
truncata 1-2 months (20 cm)
ampullaria 2-3 months (8 cm)
vikings 1-2 months (6 cm)
"thorelli" 1 month (10 cm)

Highlanders
ramispina 6-10 months (10-14 cm)
adrianii 6+ months (10-15 cm)
tobaica 6+ months (10-15 cm)
sibuyanensis 4-5 months (3 -10 cm)
sanguinea 2 months (10 cm)

So, what are your experiences?
