Plants make can make a  beautiful addition to any room’s decor.  Here are a few tips from Style on a Shoestring to help you choose and arrange your plants. 
 
First you want to choose plants that fit in with your existing decor. For instance, if you have a contemporary style, you would choose plants that are long and sleek, with slender shapes. If your home is Victorian in style, you may want to choose more “feminine” looking plants like ferns.  If your home has a Southwestern feel to it, you may want to look at plants from the cactus family. 
 
Grouping your plants for extra impact is a great look and an easy way to fill up a corner. Make sure the plants in a group vary in height for the most pleasing outcome. If you’re using live plants, choose plants that have similar lighting and watering requirements to make life easier. Then you can keep them on the same watering schedule.

You don’t want to place a 7 foot or taller tree  next to a short plant. . It’s better to graduate down with less of a drop off. The scale is wrong and it would look too severe. An easy-to-make platform for pots is a grouping of bricks covered with coordinating fabric from the room. If one of the plants isn’t tall enough, place it on a brick or a flat basket turned upside-down.
You can also group a number of plants in a single container for a different look. Use any large container, like a basket or trunk. Remember to choose plants with similar watering needs. Try using plants from the same family. For example, group different ferns together, or use the same plant with different color variations for more variety. If your color palette in the room is cool, choose plants that are dark green, not a yellow green.

Adding plants to a bathroom can create a tropical or spa-like ambience. To adjust the heights, raise the bottom of a deep container with rocks or bricks so the plants will be more visible. Line the container with heavy plastic, like a garbage bag. (Even with the lining, however, you will probably want to remove your plants to water them at the sink for the best safety and thorough watering.)
 
Balance and scale are important when placing plants in a room. You don’t want to overpower a wall, but neither do you want to plants to look lost in the space. Choose plants heights and fullness based on the space and the height of other elements in the room, such as windows, armoirs, doors and so forth.
