Sarracenia purpurea has the largest range of any tubular plant, occurring in Mississippi, Alabama, Florida and Georgia in the south. Then stretching down the entire east coast through South and North Carolina, Virginia and all other coastal states to Canada. Canada has the largest range, extending from eastern Newfoundland to western Alberta.
North of New Jersey only Sarracenia purpurea ssp. purpurea is still widespread, it is absolutely hardy and particularly suitable for the bog bed. South of New Jersey only Sarracenia purpurea ssp. venosa is found, the forms from Virginia and the Carolinas are also very suitable for the bog bed.
On the Gulf Coast in Florida, Alabama and Mississippi, Sarracenia purpurea ssp. venosa var. burkii ( or Sarracenia rosea) is most common, they grow very large, but are not very hardy and should not be planted in the bog. Since they prefer a humid warm climate, they are perfect for the windowsill.
The size of the red tube plant is very variable, especially the southern forms can reach up to 50cm and more in diameter, while in the north there are also small forms that reach just 12cm in diameter.
The flower color ranges from a light pink to a deep dark red, but occasionally yellow-flowered variants also occur.

In several cases, the Red Hose Plant has been anointed by plant enthusiasts in suitable locations outside its natural range. Some of these sites are naturalized, the oldest known one in the Swiss Jura is about one hundred years old. In addition to this, anointments are also found in Germany in Middle Franconia (thirty years old), Lusatia (thirty years old), North Rhine-Westphalia, and the Bavarian Forest. The occurrences are considered vital, with plants reaching sizes of up to 45 centimeters and coverage of up to 50%. As the red hose plant is a competitor for native bog species, it was placed on the black list of invasive species (early warning list) in Germany in 2013 and removed during maintenance measures.
Other salvages can be found in Europe in Ireland, in the English Lake District, in Sweden, and in the USA on the coast of Mendocino County, California.
