I remember my mom having a lot of plants around the house. They hung from painted hooks in the ceiling, sat on step ladders or on doilies on top of antique hutches. Fake plants have come a long way but there's nothing that can compare to a real, live potted plant in an interior. Even if you're guests can't tell the difference, to me there's something really romantic and organic about caring for a living decoration. Even if it doesn't bloom, even if it has an awful name like "spider plant", seeing that spot of green is very comforting.
