Wow. These are real nice. I wonder if it is an environment factor or it is genetics. Did you say they are grown in full sun area?
I believe I bought this before at nursery near my house years ago when I started on my first pitcher plants. Not knowing much, I got some mealworms (dried) for free from my petstore friend. Stuff my nep. A couple of days later, the nep died as well.
I hardly see these anymore. I think that would be easily 5 - 6 years ago.
BTW. Off topic. Were you the one I met today at Fauzi's stall?
