They give the place a finished look, a welcome feeling and an atmosphere of unity. With the variety of interior foliage available, plants are also a versatile tool for decorating. As a room divider, plants fill the gap with finesse. Place a sofa table along the back of the upholstered piece and fill it with plants. Now you've divided the room with a hard-line sofa, softened the division with the plants, while keeping the open feeling originally intended for the room.
Etageres are another way to divide a room.
Plants interspersed among the shelves and between other knickknacks provide a loving interlude between the areas to be divided. Instead of covering it with draperies, try hanging a few plants in front of it. Another variation of this theme is to run glass shelves across this window and place several potted plants on them. Be sure to have all the pots match in order to avoid a messy, cluttered look. The attention should be on the plants, not the pots.
