A gorgeous cross I have wanted ever since I saw it in Peter D'Amato's book "The Savage Garden". Unfortunately also my first time dealing with root rot in Nepenthes! :(
Peter D'Amato: "Dr. Marabini in Germany did the cross, which I was told was N. lowii x ventricosa. He sent seed to several growers around the world, including Bill Baumgartl in California. Bill grew out some of the plants over several years. He chose this clone and named it after me. He told me the grex was called N. x briggsiana after, I believe, John Briggs, a Nepenthes hunter. So this clone is technically called N. x briggsiana variety 'Peter D'Amato'. The plant is female."
