When deciding to purchase an artificial tree, you need to know what type of tree you like such as a topiary, a tropical tree, a ficus tree, etc. Check out Pacific Silkscapes resource page for more ideas. You also need to know what height you are looking for and how much space you have in order to determine the width. For instance, if you have 10 ft ceilings, a 6 ft tree would be too short, whereas an 8 ft tree would look perfect. You also want to make sure the tree is wide enough and not too wide to fit in your space. Lastly, you need to determine what kind of planter you want and what color matches your décor.
