Sarracenia x moorei
Sometimes, when two pitchers plants love each-other very much, they make a baby pitcher plant – like Sarracenia moorei. Arguably greater than the sum of its parts, S. moorei is a common grex name used to describe the cross of S. flava and S. leucophylla. A grex name is a common name for the collective (‘herd’) of hybrids stemming from a given set of two (or more) commonly paired parent species. In short, any hybrid between a pure leucophylla and flava is considered a moorei.
Sarracenia moorei hybrids frequently display an exceptional heterosis, or hybrid vigor. This means that the genetic diversity introduced by hybridizing these two plants commonly results in a greater size, color, speed of growth, and propensity to divide than what can be expected of either individual parent. For example, a S. moorei cross can inherit and enhance color from a leucophylla parent while producing pitchers larger than either parent. In essence, it’s the all-natural plant steroid. Moorei’s can be especially magnificent when you mix parents with distinct genetic traits.
Within the grex of moorei, there are definitely standouts that have earned the registered and coveted “cultivar” status – like S. ‘Saurus’, S. ‘Vintner’s Treasure’, or suspected naturally-occurring hybrids like S. Leah Wilkerson (though this cannot be conclusively proven at this time).
