Sarracenia flava var. rubricorpora, Yellow Trumpet Pitcher Plant (red tube variant) in habitat, Apalachicola National Forest, Liberty County, Florida
Though these plants very much resemble S. flava var. atropurpurea - they are actually the var. rubricopora. During years in which there is adequate water (which extends the growing season of this species considerably) older tubes will transition to an entire red coloration prior to senescence.
Please observe the one photo that depicts a single newly emerged tube beside an older tube of the same plant. The new tube has a yellow lid and throat whereas the older tube is entirely red.
In the much rarer var atropurpurea, the entire red coloration of the tube is observed as soon as the pitcher fully inflates and matures.
