Sarracenia flava var. rubricorpora, Yellow Trumpet Pitcher Plant (red tube variant) in habitat, Apalachicola National Forest, Liberty County, Florida
Note the newly emerged late summer pitcher (rare for S flava) beside an older pitcher from early summer. these pitchers are from the same rhizome. the redness of the old pitcher is simply senescent change and may commonly be confused with var. atropurpurea in late summer in seasons when pitchers persist.
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.
In the much rarer var atropurpurea, the entire red coloration of the tube is observed as soon as the pitcher fully inflates and matures.
