For those folks that are familiar with Sarracenia, you know they bloom in a particular order. This staggering of peak flowering times help to reduce hybridization in nature. That said, we can still find many natural hybrids in the wild due to flowering time overlap.
S. flava tends to be first in flower, shortly followed by purpurea… hence there is a decent chance for flava x purpurea hybrids to be found… however a species like psittacina is one of the last to bloom, so a naturally occurring psitt x flava hybrid is extemely rare (though has been found in Bay Co. Florida). While psitt x minor hybrids are quite common as these two species tend to bloom close to each other.
As far as flowering goes… this season has been interesting here in zone6b. The first few weeks of May were quite warm and flava and purpurea came into flower quite rapidly. Then things cooled down… these early flowers held on longer than normal due to those cool temperatures. Then things warmed a bit and then all the other species started to bloom. So this year, all species of Sarracenia were in bloom at the same time! except psittacina and minor… however they were close.
Flowering is almost done now…. but it was very colorful while it lasted. Here a couple of photos from a couple of weeks ago.
