Does anyone have a list giving the expected lenth of time a flower should last for each species of Paphiopedilum? Is it all in the genes or does culture play a part? I know it varys from species to species, but does it vary from plant to plant? Should all members of the same subgenus last the same amout of time? For instance my P. armeniacum lasted 11 weeks, yet a P. micranthum only lasted a week and a half. A P. barbatum 10 weeks, yet a P. venustum only 5 weeks. None of the books mention this and if they do it is usually a casual " long lasting " or " short lived ". Thanks in advance for any input.
