This is an interesting hybrid of several lowland-growing Nepenthes species; and the specific features of the parents are spectacular! Nepenthes mirabilis var. globosa (previously called Nepenthes 'Viking') produces round, tubby pitchers with pronounced 'wings' on the outside of the pitchers. Nepenthes ampullaria also produces tubby pitchers, but with no wings and a diminutive hood that does not even cover the pitcher opening. And adult Nepenthes rafflesiana plants can be well over three feet across, with pitchers up to a foot tall and as big around as a baseball! This particular variety of N. rafflesiana (var. alata) produces undulating 'wings' that extend up the pitcher tendrils. These are seed-grown individual clones of this three-species hybrid, and we expect individual plants to show varying degrees of these traits as they mature. No two will be exactly alike...very neat! Since these are seed-grown plants, there will be male and female plants in the mix too. All our plants are shipped potted and ready to grow to reduce stress, not bareroot as you find with some other suppliers. Water and enjoy!
