spicieangel: Did some research and found this:- Along with its ease of growth, Lucky Bamboo has long been associated with the Eastern practice of Feng Shui - Lucky Bamboo is believed to be an ideal example of the thriving wood and water element, with the addition of a red ribbon sometimes tied around the stalks - which is believed to "fire" the positive flow of energy. The number of stalks also has meaning : three stalks for happiness; five stalks for wealth; six stalks for health. Four stalks, however, are always avoided.
Hope this helps.
