To provide the decoration of a garden using optical fibers to exhibit the garden in the night decoratively and fantastically.

In order to create the fantastic scene of a garden in the night by combining darkness and brightness to make the garden not too dark and not too bright, hundreds of thin optical fibers 1 are used. The fibers 1 are fixed to synthetic resin nets 2 which are arranged at important positions in the garden. In the daytime, in order not to deteriorate the natural beauty of the garden, the optical fibers 1 are concealed with moss, undergrowth, or pebbles excluding their light emission parts 3. The fibers 3 are bound from the backside of a concealed part and connected to a light source and fixed. A household power source of 100V or the combination of solar cells with batteries can be used as the power source for the light source.
