Clas Bergvall did his PhD dissertation on the subject of what house plants do for people.
– Americans spend ~$147 on house plants each year
– Plant filled rooms contain 60% fewer airborne molds and bacteria
– Poinsettia is the favorite indoor flowering plant
– Best plants for decontaminating the air and balancing humidity are: Areca, Reed and Dwarf date palms, Boston ferns, English ivy and Peace Lilies.
But most important is that house plants bring us closer to nature.
