I'm growing CPs in the Desert of Tucson, Az
I believe my N. belli x ventricosa (male) has the longest tendril (given the plant/pitcher size) of all my collection and I really like it! I don't know if they stopped for hitting things (used pots moved for photos) or if this just happened to be the right length. Do you like them? What is (let's see) your longest! Do you think the tendril hitting things triggers the pitcher (to some extent)?
