oh, and if anyones interested:
all pitchers developed resting on moss.
1st pitcher=8cm (was 9cm when it opened, but it is 8cm now. probably due to the wrinkling, its pretty old aready)
3rd pitcher=10.5cm (newly opened)
n. hybrid (probably tobaica):
all pitchers dangleing in mid air.
6th (still developing)=3.5cm
i guess that sometimes, the pitchers just vary randomely in size... i have also noticed that the 4th pitcher on my tobaica, which is smaller than the other ones, developed in the shade of a above leaf. maybe more light can also increase growth. Zongyi
