In traditional fung shui, wood represents romance. Thus, to stimulate one's love life, plants can be placed in the sectors that are associated with the appropriate flying stars. Cut flowers are not recommended because their wood energy is much weaker, hence the blooms expire within a few days. Artificial plants are also considered ineffective as there is no life energy, or living chi, present within them. Similarly, wooden furniture is thought of as dead wood in fung shui and therefore does not have any curative effects. The interactions between the five elements can also be controlled by the presence of wood. For instance, when the stove and sink are directly opposite each other in the kitchen, the fire and water elements clash, manifesting in discord between the home's occupants. Wood can be placed between the two as water produces wood, which then feeds into fire via the productive element cycles. Instead of using plants, the colour green can be used to stimulate wood energy. A green mat, for example, should suffice in this regard. Be wary of placing wood in certain sectors of your home as it may stimulate aggressive energy associated with lawsuits and arguments. Nor should plants be placed in bedrooms, as the associated yang energy will cause insomnia, anxiety and fatigue for the occupants.
