Bloody Mary is a horticultural cross between Red Nep. Ampullaria and Red N.Ventricosa. It is more commonly sold now in Bio-Domes as Lady Luck, but I prefer the old name.
I find it stays bushier than most Nepenthes, both of mine have several basil shoots. It’s the only one I have the flat out refuses to put out pitchers all winter. It does make up for it in the summer.
Nepenthes want distilled or at least very soft water, no fertilizers. These are swamp plants so I keep 1/2″ – 1″ of water in the bottom. They seem happiest in sphagnum moss. I find they like the orchid baskets best. I think the air helps keep them from getting too soggy.
I have it in a south west window, it seems to like more light than my other Nepenthes.
