"heliamphora" is a member of the sarraceniaceae, a new world family in the order ericales (heathers and allies). "heliamphora" is limited to south america, but the family contains two other genera, "sarracenia" and "darlingtonia", which are endemic to the southeastern united states (with the exception of one species) and california respectively. "sarracenia purpurea" subsp. "purpurea" (the northern pitcher plant) can be found as far north as canada. "sarracenia" is the pitcher plant genus most commonly encountered in cultivation, because it is relatively hardy and easy to grow.
