Perry,
though I don't grow N. villosa, I have a N. macfalanei that for the last two
years has not grown beyond its 1/2 inch diamater and consistently
yellow-green in color. All the other plants in its vicinity grow relatively
fast - even the N. edwardsiana that is right next to it. It grows at about a
rate of 1 leaf every two monthes which is similar to the rate of a N.
veitchii. The N. tobaica and the N. bicalcarata that I received at the same
time as I received the N. macf. are double the size they were when I received
them.
It sounds like you are wondering if you have some sort of nutrient deficiency
that is affecting your plant. I was wondering the same thing about mine, but
now I think it is more a lack of food (insects etc.) that is small enough to
fit into the traps. Sure, I have fungus gnats but they rarely find it into a
pitcher. I am planning get some Drosophilla melanogaster from Car.
Biological Supply Co. to see if they would grow faster with natural
nutrients. After all, they *carnivorous* for a reason.
