Fresh flowers in the living room or dining room can create positive yang energies and brings pleasant ambiences into the home. Flowers are very useful in creating good feng shui, but there are some basic rules we should observe. Fresh flowers should be disposed of as soon as they start to wither as anything dead or decaying indicates a symbol of negative energy. For this cause, I always mention displaying or using dried flowers in flower arrangements should be avoided. I would instead use fake flowers than dried flowers since the fake flowers signify yang and life energy while the dried flowers represent yin and dead energy.
Flowers can be used to enhance the energies of a room. Generally speaking, flowers are suited in all parts of the house, including bedrooms and shared spaces. Flowers and plants bring yang energies into the space, and this generates yang and positive energies. They can fill the sick with joy and positive. Imagine putting in an auspicious direction; it could help the house or (wealth area) businesses with more energy.
